摘　　要：掺杂双相纳米晶复合玻璃是近十年发展起来的一种新型的面向前沿光子学应用的光学材料。这一类材料是通过热处理原位析晶或者外掺纳米晶的方式在玻璃中均匀地镶嵌两种不同种类的纳米晶体,如氟化物(YF3)、氧化物(Ga_(2)O_(3))、钙钛矿(CsPbBr_(3))以及贵金属(Au)纳米晶等,其显著的特点是兼具两种纳米晶体各自的光学功能以及玻璃自身优良的物理、化学和机械加工特性,因而有望在多个领域,如照明、显示、激光、通信、光存储和传感等得到广泛的应用。本文全面回顾了稀土和过渡金属离子单掺或共掺模式下双相纳米晶复合光子玻璃的研究进展,并从对发光性能调控的角度出发,进行了三方面的总结,即:通过调控发光离子的间距影响能量传递机制;通过构造多种晶体场环境拓展发光离子的发光带宽;通过调控发光离子局域光子态密度增强其发光效率。同时,对掺杂双相纳米晶复合玻璃的一个典型应用,即利用多模式发光实现高精度光学测温进行了总结。最后,分析了现阶段双相纳米晶复合玻璃研究中存在的一些问题,并对其发展前景进行了展望。Luminescent ions-doped dual-phase nanoglasses are a new kind of photonic materials for cutting-edge research developed in the past ten years.They are obtained via in situ crystallization or external nanocrystals(NCs)doping in glasses.The remarkable feature of such kinds of materials is that there are two different kinds of NCs in the glass matrix such as fluoride(YF3),oxide(Ga_(2)O_(3)),perovskite(CsPbBr_(3)),or noble-metal NCs.They exhibit both advantages of glasses(inertness,robustness,and ease of manufacture)and crystals(optical functions).Thus,they have a wide range of applications in solid-state lighting,display,laser,communication,optical data storage,sensing,etc.In this study,we review the research progress of dual-phase nanoglasses according to their specific applications in photoluminescence(PL)regulation,which can be classified into three classes:1)controlling energy-transfer processes by adjusting the spacing of luminescent ions;2)providing multiple crystal-field environments to broaden PL emission band;and 3)modifying local electromagnetic field enhancement factors and density of optical states to enhance PL emission intensity.However,a comprehensive review of the typical application of dual-phase nanoglasses is presented as a high-precision optical temperature measurement using multiple-mode PL emissions.Finally,we have suggested the problems or obstacles encountered in present-day research and future development directions.
