摘　　要：稀土离子掺杂微晶玻璃兼具晶体材料优异的光学特性和玻璃材料良好的物理化学特性,是一种极具发展前景的红外发光材料。本文从微晶玻璃的透过率出发,结合散射理论对其影响因素进行了简要分析,指出实现透明微晶玻璃的基本条件。分析归纳了目前稀土离子掺杂红外微晶玻璃的现状和特性,包括氟氧硅酸盐、碲酸盐和锗酸盐微晶玻璃体系。介绍了稀土离子掺杂红外微晶玻璃的应用研究进展,最后对其发展状况进行总结及展望,为稀土离子掺杂红外微晶玻璃的研究提供思路和参考。The infrared wavelength of 1-5μm contains important communication and atmospheric transmission window,which has great application value.At present,the luminescent materials used in this band mainly include rare-earth ion-doped crystal and glass.Because of the large absorption and emission cross section and low phonon energy,crystal material is widely used in the field of solid state lasers.However,the long preparation cycle and limited sample size restrict its further development.Glass material possesses excellent machinability and good fluorescence characteristics,being widely used in communication,laser and other fields.Oxide glass is mainly used in near-infrared(NIR)range being limited by its large phonon energy.Rare-earth ion-doped fluoride glass can be used in visible and mid-infrared(MIR)range,but limited by its poor chemical and mechanical properties.Rare-earth ion-doped glass ceramics shows excellent optical properties from crystal materials,and good physical and chemical properties from glass materials,making it a promising infrared luminescent material.One of the most important properties of glass ceramic is the transmittance,as the crystalline phase in glass would cause light scattering inevitably.Based on the scattering theory,one could find that the influence factors of transmittance of glass ceramics include the size and distribution of the crystalline phase and the refractive index difference between the crystalline phase and the glass phase.To realize transparent glass ceramics,the size of the crystalline should be less than 30 nm,and the refractive index difference should be less than 0.3.The status and characteristics of rare-earth ion-doped infrared glass ceramics,including oxyfluoride silicate,tellurate and germanate glass ceramics,were summarized and analyzed.The application and research progress were overviewed.Oxyfluoride silicate glass ceramics is the most widely investigated material.Phase separation would generally happen,leading to the formation of fluorine-rich nanophase before the cr
