Abstract

We have established the key trends in the variation of the intensity of the visible and IR luminescence of (Y1 − x − y − zYbxTmyErz)2O2S solid solutions in relation to their composition under laser excitation at λ = 0.940 μm. The results obtained have been used to develop multifunctional anti-Stokes white phosphors with various tinges and a predetermined relative intensities of visible and IR emission bands.
