| 摘 要： | 能量传递是发光材料中的重要现象。本文使用时间分辨光谱和发射光谱对ＮＰＢ（二胺衍生物）掺Ｒｕｂｒｅｎｅ（５，６，１１，１２－四苯基四苯并）有机薄膜的能量传递过程进行了研究，建立了动力学方程，得到了与实验值相拟合的结论。找到了产生白光的最佳掺杂比。然后制成带锁定层结构为ＩＴＯ／ＣｕＰｃ／ＮＰＢｌ：Ｒｕｂｒｅｎｅ／ＴＰＢｉ／Ａｌｑ／Ｍｇ：Ａｇ薄膜电致发光器件，结果却得不到白光发射，说明能量传递过程在电场

| Abstract: | The effect of energy transfer is an important phenomenon in lumi- nescence material. Energy transfer between 5, 6, 11, 12 -tetraphenyltetracene (Rubrene) and N, N'-bis-(1-naphhyl)-N, N' -diphenyl-1,1'-biphenyl-4,4'-diamine (NPB) has been studied in organic thin film by time-resolved spectra and emis- sion spectra. The dynamics equations were discussed to explain these process, and the solutions obtained can be compared to the computer simulation with the experimental results. White light emission can be produced by adjusting the concentration of Rubrene in photoluminescence.However,with devices of structure ITO/CuPc/NPB:Rubrene/TPBi/Alq/Mg:Ag with a blocking layer, the white light emission can not be obtained by adjusting the concentration of Rubrene in elec- troluminescence, The mechanism of energy transfer has some difference in electric field. |
