摘要
用溶胶-凝胶法以掺杂方式制备了含有铕-水杨酸-邻菲罗啉配合物的Si O2凝胶玻璃复合发光体,研究了该复合发光体的荧光和热稳定性.与配合物固体粉末相比较,结果表明将配合物引入凝胶玻璃中,其热稳定性明显提高,而其特征荧光基本保持不变.这可能与配合物所处的与外界隔绝、化学惰性的环境有关.
A ternary Eu(III) complex with salicylate (sal^-) and o-phenanthroline (phen) is synthesized and incorporated by silica matrix by sol-gel method. The thermal stability and fluorescence spectra of the gel phosphor are measured, The results indicated that the thermal stability of Eu(sal)3 (phen) is enhanced greatly through the introduction of the complex into silica matrix and the luminescence intensity remained unchanged, An isolated and chemical inert environment of the complex appears to be responsible for the thermal stability enhancement in silica gel.
