Problems solved by technology

K 3 QUR 6 Crystals have lower phonon energy than fluoride, and are more suitable as rare earth-doped upconversion luminescent hosts, rare earth ion-doped K 3 QUR 6 crystals have higher upconversion efficiency than fluoride crystals doped with rare earth ions, but K 3 QUR 6 Crystals are easy to absorb moisture, require special handling and storage, are difficult to prepare, and have poor chemical stability and mechanical strength, which affect the practical application of up-conversion luminescent materials.
But there is no trivalent rare earth ion Yb 3+ 、Er 3+ 、Tm 3+ and Ho 3+ Doped K 3 QUR 6 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 K glass used as an up-conversion luminescent material 3 QUR 6 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. 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 material, mainly because the lower phon...
