利用旋涂法制备了新的偶氮染料掺杂薄膜,在室温下测试了该薄膜的吸收光谱、稳态荧光光谱和时间分辨荧光光谱,研究了荧光衰减动力学过程,得到了反式和顺式异构体的激发单线态(S1)的荧光寿命。

A new azo dyedoped poly (methymethacrylate) (PMMA) film has been prepared by means of spincoating method. Absorption, steadystate fluorescence and timeresolved fluorescence spectra of the film have been measured. The kinetics of the decay process of fluorescence has been studied. The excited singlet (S1) state lifetimes for trans and cis isomers of the film at room temperature have been obtained.
