本論文以刮刀塗佈之技術製備紅磷光及黃磷光有機發光二極體，首先，先探討以氯苯為發光層溶劑的紅磷光元件在各有機層的下料參數及厚度，確定好下料參數值，再調整紅磷光客發光體CS90134與主發光體比例調配，最後再進行發光層為溶劑氯苯與氯仿之比較，得出此兩溶劑對電性沒太大影響，僅膜面有些許差異。第二，測試氯苯為發光層溶劑的黃磷光元件，其客發光體分別為PEY-01及PEY-02，本節先各自測試PEY-01及PEY-02與主發光體之比例調配，得出了PEY-01: TCTA : SPPO13 及 PEY-02 : TCTA : SPPO13 = 7:41:52 皆有較佳的電性表現，再混和PEY-01及PEY-02進行主客發光體之比例調配，最後得出電性表現較優秀的為比例PEY-01 :PEY-02 : TCTA : SPPO13 = 3.5 : 3.5 : 41 : 52 ，而膜面表現則是5 : 5 : 40 : 50 之比例最佳，接著，探討主發光體材料ETM-N04與SPPO13之比較，最後得出PEY-01及PEY-02混和之黃磷光元件較適合以SPPO13作為主發光體材料。第三，為陽明合作計畫調整元件參數提升元件效率，先測試不同發光層溶劑為氯苯與氯仿在電洞傳輸層於常溫與事先加熱情況下之下料反應，最後得出電洞傳輸層事先加熱至60°C再下料刮塗對元件並沒有益處，接著進行不同發光層溶劑為氯苯與氯仿所製做之元件壽命的比較，最後以氯仿為發光層溶劑之元件壽命69小時勝過氯苯為發光層溶劑元件的壽命54小時為實驗結果。

In this thesis, red phosphorescent and yellow phosphorescent organic light-emitting diodes are prepared by the technique of blade coating. First, the blanking parameters and thickness of each organic layer of the red phosphorescent element using chlorobenzene as the solvent of the luminescent layer are discussed, and the blanking is determined. Parameter value, adjust the ratio of the red phosphorescent guest luminous body CS90134 and the main luminous body, and finally compare the luminescent layer solvent chlorobenzene and chloroform, it is concluded that the two solvents have no much influence on the electrical properties, only the film surface is slightly different. Second, test the yellow phosphorescent element using chlorobenzene as the solvent of the light-emitting layer. The guest luminous bodies are PEY-01 and PEY-02 respectively. In this section, we will first test the ratio of PEY-01 and PEY-02 to the main luminous body. PEY-01: TCTA: SPPO13 and PEY-02: TCTA: SPPO13 = 7:41:52 have better electrical performance. Then mix with PEY-01 and PEY-02 for the ratio of host and guest luminaires, and finally, It is concluded that the ratio of PEY-01: PEY-02: TCTA: SPPO13 = 3.5: 3.5: 41: 52 is the better electrical performance, and the film surface performance is the best ratio of 5: 5: 40: 50. Then, Discuss the comparison between the main luminous body material ETM-N04 and SPPO13, and finally, conclude that the yellow phosphorescent element mixed with PEY-01 and PEY-02 is more suitable for SPPO13 as the main luminous body material. Third, for the Yangming cooperation project to adjust component parameters to improve component efficiency, first test the reaction of different light-emitting layer solvents, chlorobenzene, and chloroform, under the condition that the hole transport layer is at room temperature and heated in advance. Finally, it is concluded that the hole transport in the layer is heated to 60°C in advance and then scraped and scraped. It is not beneficial to the device. Then compare the life of the device made of different light-emitting layer solvents, chlorobenzene, and chloroform. Finally, the life of the device with chloroform as the light-emitting layer solvent is 69 hours better. Perchlorobenzene is a solvent for the light-emitting layer. The life span of the element is 54 hours as an experimental result.
