可撓性全彩有機發光二極體
Flexible Full-Color Organic Light-Emitting Devices
摘要
有機發光二極體具有高效率、廣視角及自發光之特性，在顯示科技應用上具極高發展潛力，隨著元件製作技術的進步，把元件製作於可撓性基板上，將可廣泛應用於日常生活中。本文以三種磷光有機發光材料Ir(pq)2(red)，Ir(ppy)3(green)，以及Firpic(blue)摻入主發光體材料SimCP，基板使用PET，於其上蒸鍍ITO作為透明電極，再採用旋轉塗佈法（溼式製程）堆疊有機發光層，最後元件以Si3N4以及SiO2多層結構封裝保護，以製作出可撓性高效率全彩(RGB)元件，且此元件結構在發光亮度爲100cd/立方公尺下擁有超過20cd/A的優良效率。

In this work, we demonstrate flexible organic light-emitting devices (OLEDs) based on the phosphorescent emitters iridium (Ⅲ) bis (2-phenylquinolyl-N, C2') acetylacetonate (Ir(pq)2), iridium (Ⅲ) cyclometalated fac-tris (2-phenylpyridine) (Ir(ppy)3), and iridium (Ⅲ) bis [(4,6-difluoropheny)-pyridinato-N,C] picolinate (Firpic) deposited in host material 3,5-bis(9-carbazolyl) tetraphenylsilane (SimCp) by the solution process reacting with indium tin oxide coated polyethylene terephthalate (PET) substrates. Introducing Si3N4 and SiO2 multi-layers as passivation layers, the devices show high flexibility and preserve high current efficiency exceeding 20 cd/A while providing brightness of 100 cd/m^2.
