| 摘 要： | 采用硅烷偶联剂KBM403对SnF2粉末进行表面改性,改性粉末的IR透射谱显示KBM403已经吸附在SnF2粉末表面,这种改性除了物理吸附外还存在微弱的化学吸附。采用溶有芪3的硅烷偶联剂KBM403对SnF2粉末进行改性,经改性的SnF2粉末有利于提高有机染料芪3掺杂的分散性。将含有芪3的改性SnF2粉末掺入低熔点铅-锡-氟磷酸盐玻璃,获得了芪3掺杂的有机/无机杂化玻璃。对玻璃的吸收、透射谱和激发发射谱进行分析,表明KBM403的介入改善了芪3在玻璃中的溶解性和分散性,减少了芪3二聚物的产生,提高了玻璃的透射率和均匀性。由于KBM403的改性减少了芪3二聚物所带来的荧光猝灭,同时KBM403与染料分子的相互作用增加了染料分子的刚性,玻璃的发光强度显著提高。

| Abstract: | In the present work,the SnF2 powder was modified by silane coupling agent KBM403.The Fourier transform infrared spectrum(FTIR) of the modified powder showed that KBM403 was absorbed on the surface of SnF2 particles through physical absorption besides a weak chemical absorption.Then the SnF2 powder was modified by the solution dissolved with stilbene 3.The modified SnF2 powder could improve the decentralization of stilbene 3 dopant. An organic-inorganic hybrid luminescence glass was prepared by doping the mo... |
