本論文主要研究有機電激發光金屬錯合物小分子材料 Bis(10-hydroxybenzo[h]qinolinato) beryllium (Bebq2)在不同蒸鍍速率(deposition rate)下成長有機薄膜的電荷傳輸特性。並將之應用於有機發光二極體元件上,探討元件的光電特性。
利用飛行時間法系統(Time-of-Flight System)量測Bebq2薄膜在不同鍍率下電子與電洞的載子遷移率(mobility, μ),發現在固定電場下隨著鍍率的增加,載子遷移率越慢。並量測在不同鍍率下的螢光強度及螢光量子效率等基本參數。在TOF技術探討下的三種不同鍍率中,將Bebq2做為有機發光二極體元件中的電子傳輸層(ETL)及發光層(EML),探討元件的光電表現特性及操作壽命(lifetime)與基本參數的
In this thesis, we report a study of charge carrier transport property of organic electroluminescent material Bis(10-hydroxybenzo[h]qinolinato) beryllium (Bebq2) with different deposition rate. Bebq2 layer with different rate applied to organic light emitting devices will be discussed.
Using the time-of-flight (TOF) technique, the drift mobilities of hole and electron of Bebq2 thin films have been measured with different deposition rate. It is found that the hole and electron mobilities show a decreasing trend with the different deposition rate. Some fundamental parameters can be measured with different deposition rate for example, the photoluminescence quantum yield and photoluminescence intensity, etc. The correlation between the fundamental parameters of Bebq2 films and the performance including B-I-V curve and lifetime of corresponding OLED with various rate are also presented.
