SiO_2凝胶中氯代苯甲酸铽稀土配合物发光性能

Luminescence Properties of Chlorobenzoic-Tb￣3+Complexes in SiO_2 Gels

采用溶胶－凝胶法，以掺杂和浸渍两种方式制备了含有氯代苯甲酸铽配合物的ＳｉＯ２凝胶发光体．讨论了不同制备条件和不同取代位置对发光强度的影响，研究了它们的激发光谱、发射光谱及荧光寿命，并与其固体粉末进行了比较．

Silica gel luminophors containing chlorobenzoic-Tb3+ complexes were prepared by sol-gel method.In which two ways were utilized,i.e:doping and immersion.The influence of preparing conditions and different substitution position on the emission intensity was discussed. Excitation and emission spectra as well as fluorescence lifetimes for the gel phosphor were measured and compared with those of solid powder samples.
