Abstract

Under 980 nm excitation, upconversion emissions originating from F32,3H36 and H34H36 transitions of Tm3+ ion in LiNbO3 single crystal were studied as a function of temperature in the range of 323–773 K. The F32,3 and H34 levels of Tm3+ ion are confirmed to be thermally coupled levels. By using fluorescence intensity ratio technique, the sensitivity of optical temperature sensor achieved in our work is higher than other reported temperature sensors. Additionally, this optical temperature sensor is well suited to high operating temperature. Tm3+/Yb3+ codoped LiNbO3 is a promising candidate for fabricating excellent optical temperature sensors.
