chi20191128上海光机所陈丹平557640Low glass transition temperature (Tg) glass with a glass transition temperature of less than 200 °C has received great attention due to its wide application in the fields of science and technology such as glass-metal sealing, electronic packaging, photon conversion and organic composite materials. In addition to the low glass transition temperature, fluorophosphate glass combines the common advantages of phosphate glass and fluoride glass, such as high coefficient of thermal expansion, perfect glassforming ability and excellent optical properties, which have attracted great interests. Tin fluorophosphate glass having a lower Tg value can be obtained by the divalent tin ions introduced into the fluorophosphate glass. At the same time, the tin ion has high polarizability to the fluorophosphate glass, which can improve the chemical stability of the glass. Tin fluorophosphate glass has gradually become a new star for the preparation of high-performance hybrid materials in recent years because it is similar to the polymer's unique network structure and low melting point characteristics which contribute to blending with polymers; tin fluorophosphate glass has also opened up new avenues as a packaging material for the field of white LEDs because of its low melting point which is conducive to blending with commercial phosphors. However, most of these studies are limited to their structure and physical properties, and there have been few reports focus on the photoluminescence properties of tin fluorophosphate glass. In this paper, the luminescence properties of tin fluorophosphate glass with low melting point will be used as the mainline to carry out the research on the mechanism and photoluminescence characteristics of its own undoped, rare earth ions and transition metal ion doping and metal halide perovskite quantum dots in tin fluorophosphate glass, which is expected to provide reference for the research and application of low melting point tin fluorophosphate glass.2020atalunwen221315284Tin-fluorophosphate glass;photoluminescence active ion;metal halide perovskite;photoluminescence propertiesStudy on Photoluminescence Properties of Low Melting Point Tin-Fluorite Phosphate Glass and Its CsPbX3 Perovskite Glass Ceramics低熔点锡氟磷酸盐玻璃及其CsPbX3钙钛矿微晶玻璃的发光特性研究玻璃化转变温度(Tg)低于 200 °C 的玻璃由于其在玻璃-金属密封、电子封 装、光子转换及有机物复合材料等科学技术领域的广泛应用而受到极大关注。除 了玻璃转变温度较低之外,氟磷酸盐玻璃结合了磷酸盐玻璃和氟化物玻璃的共同 优点,如高热膨胀系数、完美的玻璃形成能力和优异的光学性能等,引起了人们 的极大兴趣。具有孤对电子的二价锡离子引入氟磷酸盐玻璃便可获得更低 Tg 值 的锡氟磷酸盐玻璃。 此外, 锡离子对氟磷酸盐玻璃的极化性大,可以提高玻璃的 化学稳定性。 近些年来, 由于其类似于聚合物的独特网络结构和低熔点特性可与 聚合物熔融共混,锡氟磷酸盐玻璃正在逐步成为制备高性能杂化材料的新星;由 于其低熔点性可与商用荧光粉共混,锡氟磷酸盐玻璃也作为一种封装材料用于白 光 LED 领域而开辟出新道路。然而,这些研究大多局限于其结构与物理性能, 关于锡氟磷酸玻璃光学性能的研究却鲜有报道。本论文将以低熔点锡氟磷酸盐玻 璃的发光性能为主线,开展对其自身无掺杂、稀土离子和过渡金属离子掺杂及金 属卤化物钙钛矿量子点在锡氟磷酸盐玻璃中的发光机理及特性研究,期待能对低 熔点锡氟磷酸盐玻璃研究及应用提供参考。锡氟磷酸盐玻璃;发光活性离子;钙钛矿;发光性能中国科学院上海光学精密机械研究所王亚杰材料学博士
