Synthesis and IR-excited luminescence of (Y1 − xTmx)2O2S solid solutions

We have studied the key features of the luminescence spectra and kinetics of (Y 1 − x Tm x ) 2 O 2 S solid solutions in the range 400–2000 nm under laser excitation at 790 and 810 nm. The results have been used to develop a series of IR phosphors “invisible” under laser excitation in the range 790–8...

Description
Summary:We have studied the key features of the luminescence spectra and kinetics of (Y 1 − x Tm x ) 2 O 2 S solid solutions in the range 400–2000 nm under laser excitation at 790 and 810 nm. The results have been used to develop a series of IR phosphors “invisible” under laser excitation in the range 790–810 nm and possessing tunable and reproducible relative intensities of three groups of IR luminescence bands in the ranges 770–840, 1360–1520, and 1650–1980 nm, respectively.
