Inorganic Materials Aims and scope

Abstract

We have identified general aspects of the variation of the decay time for the IR Stokes luminescence of (La1 − x − y Nd x Pr y )2O2S solid solutions under pulsed excitation at a wavelength of 0.810 μm. The results have been used to develop a new, lanthanum-oxysulfide-based IR phosphor with a luminescence decay time tunable from 50 to 107 μs in the ranges 1.03–1.12 and 1.30–1.45 μm.
