A new yttrium oxysulfide-based multispectral IR phosphor activated with Nd3+ and Yb3+ ions

We have identified the main general trends of variations in the spectral and kinetic properties of the Nd 3+ and Yb 3+ IR luminescence bands in (Y 0.99– x Nd 0.01 Yb x ) 2 O 2 S solid solutions under excitation at wavelengths of 0.810 and 0.940 µm. Using these results, we have developed the first mu...

Description
Summary:We have identified the main general trends of variations in the spectral and kinetic properties of the Nd 3+ and Yb 3+ IR luminescence bands in (Y 0.99– x Nd 0.01 Yb x ) 2 O 2 S 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.
