在具有电致发光（ＥＬ）的有机整合染料８－羟基喹啉铝（Ａｌｑ３）中接以染料罗丹明６Ｇ（Ｒ６Ｇ），用真空热蒸发的方法制备器件，获得了峰值波长５７５ｎｍ的黄色直流薄膜电致发光，从而通过掺杂改变了发光颜色．并在Ａｌｑ３发光层不同区域插入一掺杂薄层（Ａｌｑ３：Ｒ６Ｇ），利用其发光波长与未掺杂部分（Ａｌｑ３）的不同，以此作为“探测层”，通过对器件光谱及电学特性的测量与分析，探讨了有关发光区域，发光机理，界面对发光影响等基本问题．
The dye Rhodamine 6G (R6G) was dipped into the organic integrated dye 8-hydroxyquinoline aluminum (Alq3) with electroluminescence (EL) and the device was prepared by vacuum thermal evaporation to obtain a yellow DC thin film with a peak wavelength of 575 nm Electroluminescence, thereby changing the luminescence color by doping. And a doped thin layer (Alq3: R6G) is inserted in different regions of the Alq3 light emitting layer. By using the difference between the emission wavelength and the undoped part (Alq3), the doped layer is used as a “detecting layer” Measurement and analysis, discusses the basic issues related to the light-emitting area, light-emitting mechanism, the impact of the interface on the light.
