Abstract: Up-conversion luminescence spectra of CaF$_2$–SrF$_2$–HoF$_3$ single crystals were investigated upon excitation by laser radiation with a wavelength of 1940 nm to the $^5I_7$ level of Ho$^{3+}$ ions. The CaF$_2$–SrF$_2$–HoF$_3$ single crystals were grown by the vertical directional crystallization method. For these excitation conditions, quantitative characteristics of the up-conversion luminescence of Ho$^{3+}$ ions were determined: energy yield, chromaticity coordinates, and correlated color temperatures. The possibility of increasing the efficiency of solar cells due to the conversion of infrared radiation in CaF$_2$–SrF$_2$–HoF$_3$ crystals was considered.
Keywords: up-conversion luminescence, rare-earth ions, fluorides, luminescence yield.
Funding agency Grant number
Ministry of Science and Higher Education of the Russian Federation FZSM-2022-0021
X-ray diffraction analysis of the studied crystals was performed with the help of a subsidy allocated to the Kazan Federal University to fulfil the state task in the sphere of scientific activity (project number FZSM-2022-0021).
