| Summary: | 碩士 === 國立臺灣大學 === 光電工程學研究所 === 94 === 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.
