Abstract

Bismuth-doped materials show fascinating near-infrared (NIR) photoluminescence (PL) properties. However, synthesizing Bi-doped, NIR-luminescent, nanometer-sized materials with high PL quantum yields remains challenging. Here, Bi-doped CsPbI3 perovskite nanocrystals (NCs) with an average size less than 10 nm and showing a superbroad NIR PL covering the telecommunication and second biological optical windows were achieved. The NIR PL quantum yield of these NCs is up to 7.17% with the Bi doping concentration of 0.074%. Additionally, efficient energy transfer from the semiconducting CsPbI3 to bismuth-related active center can be realized. We anticipate that the developed systems may find applications in optoelectronic and photonic devices as well as biological imaging. This work enriches the bank of Bi-doped luminescent materials, and might stimulate research interest for synthesizing other classes of Bi-activated nanomaterials.

1. Introduction

Bismuth-activated near-infrared (NIR) luminescent materials have attracted considerable attention in recent years owing to their huge potential for the applications in the fields of telecommunications and biomedicine [1]. Until now, NIR photoluminescence (PL) has been observed in a diversity of matrices including glasses [2–10], crystals [11–19], ionic liquids [20], and molecular crystals [21], and applications of these systems for lasers, amplifiers and bioimaging have been demonstrated [22,23]. Obviously, we can view these reported systems almost as bulk materials or powders with sizes larger than 100 nm. For some applications such as bioimaging, realizing high-efficiency NIR PL from nanocrystals (NCs) is of paramount importance, but remains challenging owing to the difficulty in the simultaneous control over the size and Bi-related NIR active center (BRACs).

Over the past several years, lead halide perovskites have emerged as a new generation of low-cost, solution-processed semiconducting materials with favorable optoelectronic properties [24]. MAPbI3 (MA = methylammonium), one of representative hybrid organic-inorganic lead halide perovskites, has been extensively investigated. Recently, we showed that Bi-doped MAPbI3 demonstrates ultrabroad NIR emission [25,26], and electroluminescence has been successfully realized using Bi-doped MAPbI3 as an emissive component. Nevertheless, MAPbI3 has intrinsic drawbacks as follows. Firstly, MAPbI3 contains organic group methylammonium, which has a strong quenching effect on BRACs, thus resulting in an extremely low PL quantum yield (PLQY). Secondly, MAPbI3 has a poor thermal stability compared to inorganic cousins such as CsPbI3. Considering that solid-state reaction can yield Bi-doped non-perovskite CsPbI3 powders and that CsPbI3 NCs can be readily produced through a wet-chemistry route [27–30], we hypothesize that synthesizing bismuth-doped perovskite CsPbI3 NCs could provide a chance for the attainment of a new class of NIR luminescent, nanometer-sized systems.

Here, we report on the synthesis of Bi-doped CsPbI3 NCs with cubic shape and cubic perovskite crystal structure. To the best of our knowledge, this represents the first work on the attainment of NIR-luminescent, Bi-activated materials with an average size less than 10 nm. The PL properties of these NCs have been investigated by steady-state and time-resolved PL measurements. In particular, we find that, by optimizing the dopant concentration, a PLQY of 7.17% can be obtained, which is much higher than that of bismuth-doped MAPbI3, suggesting huge potential for applications in optoelectronic devices or as biomarkers in the second biological window.

2. Experimental

Both Bi-doped and undoped CsPbI3 NCs were synthesized following the hot-injection method reported by Protesescu et al. with some modifications [30]. Cesium oleate (Cs-oleate) was prepared by reacting cesium carbonate (0.4073 g) with oleic acid (2mL) in octadecene (20 ml) solvent. The mixture was under vacuum conditions and heated at 120 °C for 1h, then maintained purging of N2 gas with continuous stirring at 150 °C until all solute had completely dissolved. Next, PbI2 (0.0867 g) and octadecene (5 ml) were loaded in a three-neck flask and maintained under vacuum condition for 1h at 120 °C, followed by addition of oleylamine (500 µL) and oleic acid (500 µL). After complete dissolution of the precursor, the temperature was raised to 150 °C. The Cs-oleate (408 µL) prepared in the above step was then injected into the contents of the three-necked flask, which was immediately transferred to an ice-water bath. The CsPbI3 NCs that formed in the octadecene were centrifuged at 3000 rpm for 5 min and the sedimentation was discarded. The supernatant was centrifuged at 12000 rpm for 5 min and then the pellet was dispersed in toluene after washed twice with hexane and once with toluene. The NCs were doped by adding BiI3 into Cs-oleate with designed Bi to Cs molar ratios of 0.1%, 0.5%, 1%, and 2%. The fresh samples were drop-casted on glass substrates for the characterizations of X-ray diffraction (XRD), NIR PL, time-resolved NIR-PL, and PLQYs. Other characterizations were obtained using the freshly prepared colloidal NCs dispersed in toluene. XRD patterns were taken at room temperature using a Bruker D8 ADVANCE diffractometer with Cu Ka radiation (λ = 1.54056 Å). The transmission electron microscope (TEM) images of the samples were collected using a FEI Tecnai G20 electron microscope operating at 200 kV. The absorption spectra were taken by a double-beam UV-Vis-NIR spectrophotometer (Cary 5000, Agilent). The PL spectra were analyzed with an FLS 980 spectrofluorometer (Edinburgh Instruments Ltd). Time-resolved PL measurements monitored at 680 nm were acquired on a Lifespec II setup (Edinburgh Instrument, UK) with the excitation of a picosecond-pulsed 507 nm laser. The time-resolved PL measurements at 1145 nm, under the excitation of nanosecond-pulsed light from the second harmonic (532 nm, 10 Hz, pulse duration: 15 ns) of a Nd:YAG laser, were performed by detecting the modulated luminescence signal with a photomultiplier tube (Hamamatsu, H10330-75), and then analyzing the signal using a photon-counting multichannel scaler.

3. Results and discussion

Figure 1(a) shows the XRD pattern of the undoped CsPbI3 NCs and Bi-doped CsPbI3 NCs, both of which can be indexed to the cubic phase, indicating that the crystalline structure of CsPbI3 remains well after Bi incorporation. Furthermore, the crystallinity of the CsPbI3 NCs does not show a noticeable change upon Bi doping. Notably, the positions of two main diffraction peaks at ca. 15 ° and 29 ° for the 2% samples undergoes a shift of 0.3° to a higher value, indicating that the CsPbI3 lattice contracts due to the incorporation of Bi3+ ions into matrices. This can be attributed to the smaller size of Bi3+ with respect to Pb2+. From the transmission electron microscopy (TEM) images and statistical distributions of the edge length in Figs. 1(b) and 1(d) and Figs. 1(c) and 1(e), we can conclude that the NCs do maintain their sizes and shape after Bi3+ doping. The actual Bi to Pb molar ratios in the CsPbI3 NCs, as determined by inductively coupled plasma mass spectrometry (ICP-MS), were 0.07, 0.36, 0.58, and 0.86% for the 0.1, 0.5, 1, and 2% samples, respectively. This evidences that a higher Bi concentration in the precursor solution favor the incorporation of Bi ions into the CsPbI3 lattice. Note that hereafter we denote the samples by their nominal concentrations. We note that Bi doping does not improve the stability of CsPbI3 NCs, and one day exposure in air can destroy the samples.

With the increasing of Bi concentration, the color of NC solution changes from red to brown. To examine the photophysical characteristics of these samples, the UV-vis absorption spectra were taken. As displayed in Fig. 2(a), the absorption spectra exhibit systematic red shift with the increase of Bi concentration, indicating that doped Bi ions could influence the electronic structure of the host. Next, we compared the PL spectra of Bi-doped and undoped NCs upon excitation at 450 nm. The CsPbI3 NCs display a narrow red emission centered at about 683 nm, which can be attributed to band-edge emission of CsPbI3 NCs. A redshift from 680 nm to 685 nm was followed by a blue shift with increasing Bi/Pb ratios. It is widely accepted that as dopant content increases, impurity levels interact with each other to form a band-like structure within the band gap of the host [31]. Given the slight shift and the substitutional doping of Bi, we thus attribute them to filling of the conduction band with extra electrons donated by Bi [31].

As can be seen, the intensity of the band-edge emission monotonously decreases with the increase of Bi doping concentration. Deep insight into the luminescence properties of these NCs come from time-resolved PL measurements. As shown in Fig. 2(b), the visible PL decays of the NCs monitored at 680 nm become progressively faster with increasing Bi concentration. The average lifetimes of the undoped, 0.1%, 0.5%, 1% and 2% samples are 124, 113, 87, 52, and 39 ns, respectively, which were calculated by the equation:

τx=0t × I(t)dt0I(t)dt
The Bi doping-induced shortened lifetimes strongly evidence the creation of new nonradiative channels for the band-edge transition of CsPbI3 NCs upon Bi doping. Similar trend was also observed in Bi-doped MAPbI3 [25]. Both steady-state and time-resolved PL results suggest the successful incorporation of Bi into CsPbI3 NCs.

Interestingly, we can detect an ultrawide emission band from 800 nm to 1600 nm peaked at 1145 nm from Bi-doped CsPbI3 NCs, as shown in Fig. 3(a). We stress that changing the excitation wavelengths cannot affect the emission lineshape. It is necessary to point out that the undoped CsPbI3 NCs do not show any NIR PL. This suggests that the NIR emission in Bi-doped CsPbI3 NCs originates from BRACs. It is noted that the lineshape and peak wavelength of the NIR PL are similar to the hybrid cousin [25, 26]. Combined with the results as shown in Fig. 2, we conclude that energy transfer occurs between the CsPbI3 host and BRACs. Assuming that the Bi doping-induced, shortened lifetime are merely due to the energy transfer from CsPbI3 host to BRACs, the energy transfer efficiencies can be roughly estimated by (τunx)/τun, where τun and τx are average lifetimes of undoped and Bi-doped CsPbI3 NCs, respectively. The calculated energy transfer efficiencies are 8.9%, 29.8%, 58.1%, and 68.5% for the 0.1%, 0.5%, 1% and 2% samples, respectively.

We further roughly evaluated the PLQYs of NIR emission in the range of 800-1600 nm for Bi-doped CsPbI3 NCs films under the excitation of 450 nm laser with a power of 10 mW using an integration sphere method [32]. Because the lack of detectors that can simultaneously measure the excitation and emission signals, we thus measured the emission intensity at visible and NIR spectral ranges by a Thorlabs PM200 power meter equipped with highly sensitive S120VC and S132C power sensors, respectively. The separation of visible (i.e., band-edge) and NIR emission was realized by using different optical filters (FELHO500 and FELHO950, Thorlabs). Totally, four emission intensities for each sample were measured. Firstly, we used the silica substrate as a reference that was fixed in the holder of an integration sphere, and the excitation power, W1, was measured by using S120VC power sensor. Secondly, the NCs film was placed in the sample holder of the integration sphere, and the power, W2, was measured using the S120VC sensor. No filter was used for the W1 and W2 measurements. Thirdly, the FELHO500 filter was added after the W2 measurement, and the power, W3, was measured using the S120VC sensor. Finally, the FELHO500 filter was replaced by the FELHO950 filter, and the power, W4, was measured using the S132C sensor. The PLQYs of doped NCs can be estimated by W4/(W1-W2 + W3). As shown in Fig. 3(a), the PLQY decreases from 7.17% to 5.16% along with the increase of Bi concentration, which are over two orders of magnitude larger than that of Bi-doped MAPbI3. The NIR decays of all Bi-doped CsPbI3 NCs films were measured upon nanosecond-pulsed photoexcitation at 532 nm. It is noted that the NCs films with a higher Bi concentration demonstrate relatively shorter lifetimes (Fig. 3(b)), which might be caused by the back energy transfer from the BRACs to the CsPbI3 matrix or concentration quenching. It is noteworthy that the lifetimes observed here are much shorter than those in other matrices [1], probably as a result of allowed transition occurring in this system. We note that such fast decays require a fast excitation rate that can be achieved by 532 nm pulsed light with a duration of ca. 15 ns.

We note that the emission lineshapes of Bi-doped CsPbI3 NCs are similar to that of Bi-doped MAPbI3 [25]. In our previous work, we attributed such emission to polaron-stabilized luminescent structural defects induced by Bi doping [25–27]. Owing to similar ionic radii of Bi3+ and Pb2+, Bi preferentially occupies the Pb site. The direct consequence of such a substitution is the introduction of electrons required to maintain charge neutrality. Meanwhile, owing to the slight size mismatch between Bi3+ and Pb2+, the replacement inevitably gives rise of the local structure distortion of the [PbI6] octahedra, thus creating NIR emission center. That is, the NIR PL can be attributed to the creation of in-gap trapping states in CsPbI3, which provides nonradiative channels of excited charge carriers when the excitation energy is larger than the band gap; the radiative transition from the in-gap state to the valence band gives rise to the NIR emission (Fig. (3c)). In contrast to hybrid MAPbI3 in which the strong C-H and N-H vibrations could cause nonradiative decays of emissive states, we surmise that the inorganic matrix of CsPbI3 NCs, without any organic group inside the matrix and well-passivated by oleylammonium ligands in the surface, favors a high PLQY. We stress that more work is necessary to gain deeper insight into the emission mechanism of this system.

4. Conclusion

In conclusion, we have realized the synthesis of Bi-activated, NIR-luminescent NCs by using CsPbI3 perovskite as a host. The synthetic method is simple and easy-to-control, and the samples demonstrate PL covering the telecommunication and second biological optical windows and with a high PLQY (7.17%). Additionally, efficient energy transfer from the semiconducting CsPbI3 to BRACs can be achieved. To the best of our knowledge, this represents the first work on the synthesis of Bi-doped NIR-luminescent NCs. We anticipate that the material system developed here could find applications in the fields of optoelectronic and photonic devices as well as biological imaging. We also expect that our work could stimulate research interest for the synthesis of Bi-doped luminescent nanomaterials, which will speed up their practical applications in a diversity of areas.
