“…Due to unique thermodynamic and crystallization parameters, chemical and optical properties, bismuth-containing systems, such as ZrF 4 -BiF 3 -MF 2 (M = Ba, Sr, Ca) and ZrF 4 -BiF 3 -MF (M = Li, Na), are intensively investigated in recent years [12][13][14][15][16]. A high radiation resistance, mechanical strength, spectral transparency and simplicity of additional optically active doping allow us to consider these systems as promising materials for IR laser radiation converters into visible light.…”

The conversion of infrared radiation of a Tm 3+ :YAP laser at a wavelength of 1.93 µm into visible light in [(ZrF 4 ) 0.4 -(BiF 3 ) 0.6 ] 100−x -(HоF 3 ) x (x = 1.5 or 5 wt%) ceramic samples was investigated. The emission bands at wavelengths of 650 nm, 900 nm and 1100 nm corresponding to transitions from 5 F 5 , 5 I 5 and 5 I 6 levels to the ground state 5 I 8 were observed in upconversion luminescence spectra. From the experimental data, an estimate of the crossrelaxation coefficient from 5 S 2 was obtained. It was K cr ≈ 1 × 10 −16 cm 3 s −1 . The threshold power density of Tm 3+ :YAP laser, at which a luminescence was observed on the ceramic samples, was about 0.85 W cm −2 .
