中文摘要：
采用对主体材料8-hydroxyquinoline aluminum（Alq3）掺杂的方法，通过对3种小分子荧光染料Dimetb-ylquinacridone（DMQA）、4-（Dicyanomethylene）-2-t-butyl-6-（1，1，7，7-tetramethyljulolidyl-9-enyl）-4H-pyran（DCJTB）、5，6，1l，12-tetraphenylnaphthacene（Rubrene）的研究，比较了其光致发光光谱和吸收光谱，利用Rorster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。研究表明，3种荧光染料同时具有F6rsterET类型和DCT类型掺杂剂的性质，并不只是一种单一类型的掺杂染料，由此推测大多数掺杂染料可能应同时属于此两种类型。
英文摘要：
The doping type of three organic small molecular dyes, dimethylquinacridone （DMQA） ,4-（Dicyanomethylene）-2-t-butyl-6-（ 1,1,7,7--tetramethyljulolidyl-9-enyl）-4Hpyran （DCJTB）, 5,6,11,12-tetraphenylnaphthacene （Rubrene） via doping into the host material 8-hydroxyquinoline aluminum （Alq3） is investigated. Comparing the electroluminescence （EL）with photoluminescence （PL） spectra of three materials and using Forster energy transfer and direct carrier trapping theory, the dopant type is discussed. The results show that these three fluorescent dyes all have the characteristics of Forster energy transfer and direct charge carrier trapping.
