摘　　要：研究了有机材料蒽和８－羟基喹啉铝(Ａｌｑ３)在固态,溶解液态和镶嵌隔离态三种状态下的发光特性,发现随着有机分子密度的降低,即从高密度态向单体状态的变化过程中,其发光峰位出现蓝移,发光峰半高宽的宽度变窄,发光峰的对称性变好．Photoluminescence (PL) properties of organic anthracene and Alq3 in solid state, in solution and in isolated insert state were studied. It was found that as the density of organic molecules decreased, i. e. the state of the organic molecules changed from condensed state to monomer, the luminescent peak shifted to the blue, luminescent width at half maximum narrowed and the symmetry of the luminescent peak was improved.

关 键 词：有机分子 光谱特性.
