摘　　要：在SiO2凝胶材料中掺杂香豆素102和若丹明6G混合染料后,二元染料之间存在着能量传递,其发光光谱比单一染料的光谱展宽.前者在SiO2凝胶基质中可调谐范围展宽到120 nm,混合染料在SiO2凝胶基质中发光光谱展宽,并且具有更高的能量转移效率.Being doped by coumarin 102 and thodamine-6G, the fluorescence spectra of SiO2 gel film is widen comparing with that there is just one kind of dopant doped, because there is energy exchange between the dopants. The scope of the fluorescence spectra can be up to 120 nm. The mixed dye can not only widen the fluorescence spectra of SiO2 gel film, but also result in high efficiency of energy transfer.
