【摘要】 对有机发光材料８羟基喹啉铝（Ａｌｑ３） 及其高分子复合物薄膜的瞬态荧光特性和跃迁机理进行了研究， 发现复合物薄膜的荧光寿命比Ａｌｑ３ 样品的寿命明显缩短， 认为荧光的产生和对激发光的吸收主要由８羟基喹啉基团引起． 而高分子基质引起的淬灭过程可能是导致复合物薄膜寿命降低的主要原因更多还原

【Abstract】 The transient fluorescence and the mechanism of electronics transition of tris (8 hydroxyquinline) aluminum (Alq3) samples and their polymer films were studied. It was found that the fluorescence lifetimes of Alq3 polymer films are shorter than those of Alq3 samples. The reductions of the fluorescence lifetimes of the polymers are attributed to the quenching by the host.更多还原
