摘要
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 DC drived EL devices have been prepaired by means of conventional vacuum vapour deposition. The emitting material of these devices is Rhodamine (R6G) doped organic chelate dye 8-hydroxyquinoline aluminium (Alq3). The wavelength of devices changed from Alq3's 523urn to 575urn. Moreover, a doped Alq3 thin film whose emission colour is different from undoped Alq3 emitting layer was used as a 'sensing layer'.The spectra and I-V character were measured and the emission zone, interface effect, energy transfer mechanism and other fundamental problen of luninescence were discussed.
