Plasmonic nanostars as efficient broadband scatterers for random lasing

Open Access Open Access

Abstract

Plasmonic nanoparticles can be used as scattering centers for random lasing. Here, we examine gold nanostars with a broadband scattering spectrum in combination with various gain media. This combination enables a huge spectral coverage of narrow linewidth emission even under a fixed excitation wavelength of 532 nm. Furthermore, we show that nanostars outperform nanoparticles of other shapes such as rods or spheres.
