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.

We have proposed, experimentally demonstrated, and implemented a technique for producing a new photostimulated blue-green phosphor with increased photostimulated luminescence intensity via additional doping of the Sr 4Al14O25:Eu,Tm phosphor with La3+. The photostimulated phosphor (FV-490M) has been commercialized and is used most widely in security and authentication applications, both as an individual phosphor and in combination with the photostimulated red phosphor SrS:Eu,Sm. When IR-stimulated, the combination phosphor exhibits a dynamic visual kinetic effect. © 2013 Pleiades Publishing, Ltd.

We have studied the key features of the luminescence spectra and kinetics of (Y1-x Tm x )2O2S 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. © 2013 Pleiades Publishing, Ltd.

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 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.

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.

We have determined the composition range of solid solutions in the binary system YPO 4-YbPO 4 and identified the key trends in the composition dependence of their IR Stokes luminescence intensity and decay time in the range 0.96-1.1 μm. The results were used to develop a new narrow-band IR phosphor, YPO 4:Yb 3+. Under 0.940-μm laser excitation, this phosphor offers an increased IR Stokes luminescence intensity in the range 0.96-1.1 μm (about twice as high as that of the well-known commercially available phosphors L-54 and FSD-546-2), with an afterglow time of 1700-1800 μs. © 2011 Pleiades Publishing, Ltd.

We have identified general relationships between the spectral and kinetic properties of the IR Stokes luminescence bands of Y 1-x-y Nd x Pr y PO 4 solid solutions in the spectral range 0.86-1.40 μm under 0.810-μm laser excitation. The results have been used to formulate technical requirements for the purity of rare-earth oxides for the fabrication of efficient YPO 4:Nd 3+ IR phosphors and to develop a fast YPO 4:Nd 3+, Pr 3+ IR phosphor that allows the decay time of the Nd 3+ IR Stokes luminescence bands in the range 0.86-1.40 μm to be tuned from 50 to 170 μs by varying the ratio of the Nd 3+ and Pr 3+ concentrations. © 2011 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.
