| 摘 要： | 研究了不同活性分子（半花菁和氐盐）混合聚集体的形成以及紫外光照射对ＬＢ交替多层膜光致荧光（ＰＬ）特性的影响。在半花菁和氐盐混合的ＬＢ膜中，由于不同分子间较强的相互作用使混合膜的荧光光谱较纯半花菁和氐盐分子膜分别发生了蓝移和红移。利用紫外光照射可以使分子的聚集体部分分解甚至破坏分子的结构，导致光致荧光强度明显减弱。

| Abstract: | Effects of the mixed aggregates of different a ct ive molecules and UV illumination on photoluminescence(PL) spectra of Langmuir- Blodgett multilayers were investigated.The strong interaction between hemicyanin e and stilbazolium salt molecules in the mixed films caused a blue or red shift of the fluorescence band with respect to that of interleaving hemicyanine or sti lbazolium salt /arachidic acid multilayers.UV illumination would dissociate the aggregates even more destroy the molecular structure,leading to a significant re duction of fluorescence intensity. |
