摘要
利用单光子计数技术,在纳秒级时间分辨荧光光谱仪上,通过真空升华超增感染料对薄膜的荧光寿命测试,并比较在溴化银单晶上形成的超增感体系的荧光寿命,研究了超增感过程中的能量传递,提出超增感剂的激子能带模型,并以此探讨了超增感机理。同时,对增感染料的固态薄膜的荧光光谱进行了讨论。
In the supersensitizing system based on AgBr Single Crystal, the fluorescence emission of the sensitizing dyes is quenched by supersensitizers. The fluorescence lifetime of the supersensitizing system is measured by single-photon time correlation method. The energy transfer process in supersensitization is discussed.
