【摘要】 利用光声光谱技术,采取猝灭的方法对(口恶)嗪1高氯酸盐的二氯乙烷溶液进行荧光量子效率的测量。发现其荧光量子效率与浓度的依赖关系与一般染料和固体材料都有明显的不同。根据分子能量转移模型,导出荧光量子效率与浓度关系的数学式,与实验结果很好地相符。更多还原

【Abstract】 The fluorescence quantum efficiency of oxazine 1 perohlorate in 1, 2-dichloro-ethane was measured with photoacoustic speetroscopy in which the fluorescence quenching wag used. The measurement shows that the relation between the fluorescence quantum efficiency and the concentration of solution of oxazine 1 in 1.2-dichloroethane is obviously different from that of some conventional dyes and solid fluorescence materials. A theoretical model was set up, it can explain the results satisfactorily.更多还原
