摘 要: 采用稳态和时间分辨荧光光谱技术,研究了非偏振紫外光照射对氐盐有机分子LB交替多层膜光致荧光特性的影响。紫外光照射可以使有机分子的聚集体部分分解甚至破坏分子的结构。 The influence of UV illumination on photoluminescence (PL) spectra of the Langmuir Blodgett multilayers were investigated by using the steady state and time resolved fluorescence techniques. UV illumination would dissociate the aggregates even more destroy the molecular structure, leading to a significant reduction of fluorescence intensity.
