本研究使用高分子材料聚(N-乙烯咔唑)(PVK)與CdSe/ZnS核殼量子點材料來製作反置白光有機發光二極體之發光層,並利用射頻磁控濺鍍系統來製作氧化鋅薄膜當電子注入層。為了獲得白光將使用不同尺寸的量子點做混合並搭配色度座標圖來找出最佳的混合比例,接著探討發光效率對於不同製程腔壓與厚度之氧化鋅薄膜的關係,再利用雷射干涉曝光和濕式蝕刻製作ITO奈米柱陣列,最後將氧化鋅薄膜成長於ITO奈米柱上,奈米柱陣列可有效增加接觸面積並大幅增加電子注入至發光層的數量,因此增加元件的發光亮度及發光效率。加入ITO奈米柱陣列週期為1.5 μm的反置白光有機發光二極體其最高發光亮度提升至16333 cd/m2,而最大發光效率提升至3.12 cd/A。
In this study, poly (N-vinylcarbazole) (PVK) and CdSe/ZnS core-shell quantum dots were used to fabricate the emission layer of the white light organic light-emitting diode and fabricated by RF magnetron sputtering. The ZnO film was an electron injection layer. In order to obtain white light, we used different sizes of quantum dots to do the mix and used CIE coordinate to find the best mixing ratio, and then discussed the luminous efficiency for different chamber pressure and thickness of the relationship between ZnO film, and then use the laser interference exposure and wet etching method to produce the ITO nanorod arrays. Finally, ZnO films were grown on ITO nanorod arrays structure. The nanorod arrays structure were effective in increasing the contact area and significantly increasing the number of electrons injected into the emission layer which promoted the luminous brightness and luminous efficiency. The maximum luminous brightness of the inverted white light organic light emitting diodes with the ITO nanorod arrays structure period for 1.5 um was increased to 16333 cd/m2, while the maximum luminous efficiency was increased to 3.12 cd/A.
