摘要
重点研究了聚(9-丁基芴)的光致发光谱线窄化特性.以不同接收方式均得到多模发射.通过激发态寿命的测量和分析,分辨出谱线窄化的不同微观机制,并在实验中观察到了产生激射的泵浦光的阈值.
The spectrum narrowing of poly (9 butylfluorene)(PBF) was studied and conformed the stimulated emitting phenomenon in PBF films, named laser action. The energy threshold of emitting laser in PBF film with ~1μm thikness was at 8~15μJ/cm 2.
