香豆素和若丹明在SiO_2混合染料凝胶基质中的发光光谱

Spectral Studies of the Binary Dye Mixture in Silica Film

实验发现,在凝胶材料S iO2中掺杂混合染料香豆素102和若丹明6G后,其光谱比只掺杂单一染料的光谱展宽,两种掺杂染料之间存在能量转换。本文就样品制备和测量结果进行分析。

Abstract：The binary mixture doped silica films were prepared by sol - gel process. The fluorescence spectra for Coumarin 102 （the donor） at a concentration of 2 × 10^-3 moL/L and Thodamine - 6G （ the acceptor） at various concentrations in ethylene glycol and in silica film were measured. The results displayed that the spectrum were wider than one single dye and there were energy transfer between C102 and Rh6G. In silica films the energy transfer efficiency was higher than that in ethanol solutions. All the results showed that the material we made can be better used in the solid laser field.
