| dc.description.abstract | 在此篇論文中，我們藉由在發光層內的不同位置插入紅光的摻雜物當作探針，去量測混和層有機發光元件內復合速率的分佈。同時，由於摻雜物比本體有較高的復合常數，因此在8伏特的電流被增加了8.12倍。藉由上述的共摻雜的方式，我們製造出了能量效率為6.2流明/瓦的白光有機發光元件。在實驗的最後一部份，我們架設了一個簡單且實用的透水率量測系統來測量可撓性基板上的鈍化層的透水率。 | zh_TW |
| dc.description.abstract | In this thesis, we had measured the spatial recombination-rate distribution of a mixed-emitter (ME) organic light-emitting device (OLED) by inserting a red-dopant at different positions of the emitting layer (EML) as a probe. The approach of thin doped-layer to the maximum recombination-rate position generated a strong red emission. In the meantime, the electrical current increases by 8.12 times at 8V due to the higher recombination coefficient of the dopant than the matrix.
Also, we designed the white OLEDs (WOLEDs) based on the co-doped technique. Consequently, a WOLED with higher power efficiency of 6.2 lm/W has been demonstrated. In the final part of my experiment, the simple and useful water vapor permeation rate measurement (WVPR) system is developed to detect the WVPR of passivation layer on flexible substrate. | en |
