Description

technical field [0001] The present invention relates to a rare earth ion doped glass ceramics, in particular to a rare earth ion doped GdCl used as an up-conversion luminescent material 3 Glass-ceramic and its preparation method. Background technique [0002] Upconversion luminescence is a process that utilizes the absorption of multiple photons to generate radiative transitions, and the energy of the radiated photons is usually higher than that of the pump photons. 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 reduce the pro...
