- Abstract
- Solid solutions based on barium fluoride doped with rare earth element ions have been obtained by solid-phase synthesis. According to X-ray powder diffraction, the obtained samples have monophase fluorite structure. Increase in the concentration of rare earth element ions leads to decrease of crystal structure volume. Laser irradiation at 980 nm (radiation power of 1.2 W/cm2) produces luminescence in the visible spectral region. The presence of Yb3+ ion as sensitizer increases luminescence intensity for barium fluorides doped with Er3+ ions. Incorporation of Tm3+ ions into barium fluoride doped with Er3+ ions leads to decrease of total radiation intensity and the predominance of luminescence in the red spectral region. Color coordinates calculated from photoluminescence data by CIE 31 standard have been determined for the samples. The obtained materials of prescribed composition can transform infrared radiation into visible light.
