摘　　要：采用溶胶 凝胶法 ,以掺杂方式制备了含有铕 (铽 ) 间甲基苯甲酸 邻菲咯啉配合物的SiO2凝胶复合发光体 ,研究了其热分解曲线、激发光谱和发射光谱 ,并与固体粉末进行了比较 ,讨论了将配合物引入该凝胶后对其热稳定性及发光的影响。Silica gel luminophors containing 1,10 phenanthroline-tris (m-methylbenzoate) europium (or terbium) complexes were prepared by sol-gel method. The thermal decomposition,excitation, and emission spectra for the gel phosphors were measured and compared with those of solid powder samples.The influences of SiO 2 host material on the thermal stability and the luminescence spectra of the complexes were discussed.
