Problems solved by technology

However, the traditional glass-ceramic preparation is to obtain a glass matrix with a specific glass composition and design a specific temperature for heat treatment to make it grow crystal grains in the glass matrix (CN101085699). This method is complicated to prepare, difficult to manipulate, and devitrifies The process is difficult to control
Moreover, the rare earth doped glass ceramics currently studied are mainly limited to the fluorosilicate glass system

One-step moulding method is adopted, the preparation process is convenient and safe, and no expensive equipment is needed.

Description

technical field [0001] The present invention relates to material preparation, especially a kind of Er containing 3+ :SrF 2 -YF 3 Mixed crystal fluorine indium glass ceramics and its preparation method. Background technique [0002] Mid-infrared solid-state lasers with a working band around 2.7 microns have attracted much attention because of their potential applications in remote sensing, air pollution monitoring, military and medical surgery. It is well known that the fluorescence emission of rare earth ions strongly depends on the phonon vibrations of the host material. At present, the research and development of mid-infrared emitting host materials has reached a bottleneck. [0003] Among them, crystal and fluoride glass are ideal host materials. Recently reported by Er 3+ Doped Y 3 Al 5 o 12 and YF 3 / YOF nanocrystals produce an effective emission of 2.7 μm, but the crystals cannot be prepared in large sizes and complex preparation processes, which severely lim...
