摘　　要：对 8 -羟基喹啉铝 (Alq3)高分子复合物薄膜的的瞬态荧光特性和机理进行了研究 ,发现复合物薄膜的荧光寿命比 Alq3样品的寿命明显缩短 ,荧光峰值波长紫移 ,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 ,而 Alq3分子与基质分子间的互作用则引起荧光峰值波长的移动。The transient fluorescence characteristics and mechanism of Alq3 compound films have been studied. It has been found that the fluorescence peak wavelengths of Alq3 compound films blueshift and the fluorescence lifetimes are shorter than those of Alq3. The reductions of the fluorescence lifetimes of the compounds are attributed to the quenching of host molecules and the blue shifts of the fluorescence peak wavelengths are asigned to the interactions between Alq3 and the host molecules.
