Problems solved by technology

At present, chloride transparent glass-ceramics is mainly used as scintillation and up-conversion luminescent materials, such as the publication number CN103382089, and the name is "Containing Cs 3 LaCl 6 Nanocrystalline transparent sulfur-halogen glass ceramics and its preparation" invention patent application discloses doped Nd 3+ or Er 3+ ions, with Cs 3 LaCl 6 Glass-ceramic is microcrystalline phase and glass phase is sulfide, but the physical and chemical properties of sulfide are worse than that of oxide, and it is not transparent at short wavelengths of visible light, which affects the output of up-conversion luminescence; for example, the publication number is CN103951233, and the name is "Rare earth ion doped LiYCl 4 The invention patent application of "glass ceramics and its preparation method" also discloses that a crystallite phase is LiYCl 4 , the glass phase is SiO 2 Mainly glass ceramics, doped with rare earth ions as Ce 3+ 、Eu 3+ , Tb 3+ 、Pr 3+ and Nd 3+ One of them, prepared by melt quenching method and subsequent heat treatment, has good scintillation performance, and is used as a scintillation luminescent material
But there is no Yb yet 3+ 、Er 3+ 、Tm 3+ and Ho 3+ Doped YCl 3 Published reports on the use of glass-ceramics in upconversion luminescent materials

Description

technical field [0001] The present invention relates to a rare earth ion doped glass ceramics, in particular to a rare earth ion doped YCl 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. Violet-blue-green 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 ...
