| 摘 要： | 利用荧光光谱对电致发光器件(OLED)中几种常用化学组分的荧光猝灭和光诱导电子转移问题进行了研究.发现两种常用的空穴传输材料NPB和TPD与常用电子传输材料AlQ3在光的帮助下可发生电子转移.根据荧光猝灭的Stern-Volmer作图和用单光子记数法测得的荧光寿命而计算得到的猝灭速度常数和扩散速度常数相对应,明确地表明这里的猝灭具有电子转移特征.并对所得的结果进行了讨论.

| Abstract: | Fluorescence quenching and photoinduced electron transfer between several common materials,hole-transporting material,TPD,NPB and electron-transporting material,AlO_3 using in OLEDs were studied.Based on the measurement of fluorescence quenching constants of these compounds and the calculation of Gibbs' free energy changing of these processes,it was concluded that the property of process studied in this work possesses character of electron transfer definitely.Compared their fluorescence quenching effect,ΔG,and T_g,NPB was thought to be a better hole transporting material than TPD. |
