摘要
本文研究了激光染料Coumarin-480,Oxazine-720,Oxazine-725在聚乙二醇介质中的荧光光谱。结果表明荧光强度随着聚乙二醇浓度的不断增大而增强,荧光发射的最大峰位有较明显的红移,表明染料分子与聚乙二醇分子间形成了分子缔合物,缔合物愈稳定,荧光强度增强愈大,红移愈大。
n this paper,the fluorescent spectra of laser dye Coumarin-480,Oxazine-720 and Oxazine-725 in the medium of polyglycol were studied.The results show that the fluorescent intensity is enhanced as the concentration of polyglycol is increased.The fluorescent peak shifts obviously towards the long wavelength.The results indicate that the molecular complex is formed between the:molecular dye the molecular polyglycol.The higher the stability of the molecular complex,The larger the increase in fluorescent intensity and red shift.
