Description

technical field [0001] The present invention relates to a rare earth ion doped glass ceramics, in particular to a rare earth ion doped K glass used as an up-conversion luminescent material 3 LuCl 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. 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 ...
