Abstract

The invention discloses Li3YCl6 glass ceramics doped with rare earth ions. The Li3YCl6 glass ceramics is prepared from 87.8-94 mol% of SiO2, 5.5-10 mol% of Li3YCl6 and 0.5-3 mol% of LnCl3, wherein LnCl3 is at least one of YbCl3, ErCl3, TmCl3 and HoCl3. The Li3YCl6 glass ceramics has the advantages of being transparent, resistant to air slake, good in mechanical performance, high in blue and purple light transmittance, low in phonon energy, high in up-conversion efficiency, capable of greatly improving efficiency of an up-conversion laser device, simple in preparation method and low in production cost.

Description

technical field [0001] The present invention relates to a rare earth ion doped glass ceramics, in particular to a rare earth ion doped Li 3 YCl 6 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 because the lower phonon energy can reduc...
