Rare earth ion doped LuCl3 glass ceramics and preparation method thereof

Abstract

The invention discloses rare earth ion doped LuCl3 glass ceramics. The rare earth ion doped LuCl3 glass ceramics are prepared from SiO2 80-91.5 mol%, LuCl3 8-16 mol% and LnCl3 0.5-4.5 mol%, wherein the LnCl3 is at least one of YbCl3, ErCl3, TmCl3 and HoCl3. The rare earth ion doped LuCl3 glass ceramics have the advantages that the prepared rare earth ion doped LuCl3 glass ceramics are transparent, are resistant to deliquescence, are good in mechanical performance and higher in blue and violet light transmittance, have the performances of low phonon energy, high upconversion efficiency and the like, enable the efficiency of an upconversion laser to be improved greatly, a preparation method of the glass ceramics is simple, and the production cost is lower.

Description

technical field [0001] The present invention relates to a rare earth ion doped glass ceramics, in particular to a rare earth ion doped LuCl used as an up-conversion luminescent material 3 Glass-ceramic and its preparation method. Background technique [0002] The up-conversion luminescence of rare earth ions refers to the phenomenon that when a sample doped with rare earth ions is irradiated with excitation light with a longer wavelength, light with a wavelength shorter than that of the excitation light is emitted. Utilizing the up-conversion properties of rare earth ions, an inexpensive fiber laser that can work at room temperature and continuously output violet-blue-green light can be obtained. Up-conversion lasers can be used in various fields such as color displays, data storage, information technology, laser printing, and medical treatment. To improve the efficiency of upconversion luminescence, it is necessary to reduce the phonon energy of the host material, mainly ...
