本研究係將聚甲基丙烯酸甲酯(PMMA)顆粒配置成混合溶液並在玻璃基板上製作出微孔洞陣列。首先我們將PMMA顆粒溶解於酯類溶劑中以形成PMMA溶液，再將PMMA溶液塗佈在平坦的玻璃基板上，接著加熱使溶劑揮發，便可在平坦的玻璃基板上形成微孔洞陣列。過程中，我們嘗試調整熱處理溫度、溶劑的種類、共溶劑的濃度、PMMA的濃度、以及旋轉塗佈的轉速。此外，我們也探討微孔洞陣列對於OLED元件效率和光學性質的影響，實驗結果顯示，微孔洞陣列促進OLED元件功率效率最高可達35%。

In this thesis, micro-hole arrays were fabricated by spin coating the solution of polymethylmethacrylate (PMMA) on glass substrates. The PMMA solution was prepared by dissolving PMMA powders into esters at first, followed by spin coating the solution on flat glass substrates. The micro-hole arrays were formed after the evaporation of solvent in the PMMA solution. Many process parameters, such as heating temperature, different type of solvent, concentration of co-solvent, solution of PMMA, and spin speed had been studied. Furthermore, the influences of micro-hole array on efficacy and optical properties of organic light-emitting diodes (OLEDs) were also discussed. The experimental results showed that efficacy of the OLED can be improved up to 35% by attaching a micro-hole array.
