carrier capture

Comparing the e- lectroluminescence (EL)with photoluminescence (PL) spectra of three materials and using F(?)rster energy transfer and direct carrier trapping theory,the dopant type is discussed.

采用对主体材料8-hydroxyquinoline aluminum(Alq_3)掺杂的方法,通过对3种小分子荧光染料Dimeth- ylquinacridone(DMQA)、4-(Dicyanomethylene)-2-t-butyl-6-(1,1,7,7-tetramethyljulolidyl-9-enyl)-4H-pyran (DCJTB)、5,6,11,12-tetraphenylnaphthacene(Rubrene)的研究,比较了其光致发光光谱和吸收光谱,利用F(?)rster能量传递(ET)理论和直接载流子俘获(DCT)理论对这3种材料作为掺杂染料的类型进行了讨论。

The Frster energy transfer(ET),direct carrier trapping(DCT)theory and electroluminescence(EL)spectra of the devices were used to discuss the type of the three dyes as the dopant.

利用Fo¨rster能量传递(ET)理论和直接载流子俘获(DCT)理论,结合器件的电致发光(EL)光谱,讨论了这3种材料作为掺杂染料的类型。
