摘　　要：采用溶胶 -凝胶法 ,以掺杂方式制备了含有均苯四甲酸铕稀土配合物的 Si O2 粉末转光材料。讨论了协同发光离子对其发光强度的影响 ,研究了他们的激发光谱和发射光谱 。Silica gel luminophors containing pyromellitic acid-Eu 3+ complexes were prepared by sol-gol method with doping. The influence of doping conditions on the emission intensity and Weather resistance were discussed.Excitation and emission spectra for the gel phosphor were measured and compared with those of pure powder samples.
