本論文是利用刮刀製程製作液態有機發光二極體，發光色光是綠色磷光的小面積元件。結構主要分為多層與單層結構，並使用不同材料，透過材料本質差異，而提升元件之操作壽命。首先是多層結構改善，若用液態製程製備多層元件，通常會造成層間互溶問題，使得元件操作壽命低落，但透過電極搭配並加上快速熱退火，使得載子注入平衡且分子能夠重新排列得更加緊密，讓元件壽命在起始亮度500 cd/m2下，壽命由5小時提升至200小時以上。單層結構是改變了電子傳輸層材料，利用材料本質上的特性，並加入具熱聚合特性之材料，使得元件操作壽命提升，在起始亮度為1000 cd/m2，其壽命提升至140小時左右，更可運用此結果在本團隊之大面積化製程上，製作出概念性之OLED原型產品。

It is consider that this thesis is research the organic light-emitting diode by solution process. The device is small area green phosphorescence organic light-emitting diode and the structure included single-layer and multi-layer. In order to improve device lifetime, it is propose variety material during the experiment.
To begin with the improvement of the multi-layer, it will induce the dissolution problem between layers and cause the lifetime decreased. It is adopt to electrode match and rapid thermal process which make the carrier injection balanced and molecules could rearrange closely. It will not only enhance two order of the lifetime and reduce the dissolution problem by using two optimized method. The second part is single layer structure, we use the different material property to replace the electron transport material and adding the material with cross-linked. When initial luminance is 1000cd/m2, the lifetime will enhance to 140 hours. It can be concluded that, we can use the result for the large area OLED product in our team.
