We have studied the effect of Er3+ concentration on the visible and IR luminescence of (Y1-x Er x )2O2S solid solutions in the range 450-1600 nm under excitation at a wavelength of 365 nm. © 2016 Pleiades Publishing, Ltd. Source

We have identified general aspects of the composition dependences of the photostimulated luminescence intensity and decay time in the range 475-525 nm for Sr3.91-x Eu0.04Tm0.05Er x Al13.36B0.64O25 solid solutions. The results have been used to develop a new blue-green photostimulated phosphor. After laser stimulation at 0.810 and 0.940 μm, it offers a longer afterglow duration in comparison with the FV-490M and FV-490DM industrial phosphors. © 2015 Pleiades Publishing, Ltd. Source

We have identified general aspects of the variation of the decay time for the IR Stokes luminescence of (La1 - x - yNdxPry)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. © 2015 Pleiades Publishing, Ltd.

We have identified the main general trends of variations in the spectral and kinetic properties of the Nd3+ and Yb3+ IR luminescence bands in (Y0.99–xNd0.01Ybx)2O2S solid solutions under excitation at wavelengths of 0.810 and 0.940 µm. Using these results, we have developed the first multispectral IR phosphors with various relative intensities of the IR luminescence bands in the ranges 0.88–0.94, 0.94–1.06, 1.06–1.12, and 1.35–1.42 µm under excitation with 0.810-µm light and bright IR luminescence in the range 0.94–1.06 µm under excitation with 0.940-µm light. © 2016, Pleiades Publishing, Ltd.

We have established the key trends in the variation of the intensity of the visible and IR luminescence of (Y 1-x-y-zYb xTm yEr z) 2O 2S 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. © Pleiades Publishing, Ltd., 2012.
