有機電激磷光材料與OLED磷光元件之發展近況

Rectent Development of Organic Electrophosphorescent Materials and Phosphorescent OLED Device

摘要


利用有機小分子產生電激發光是目前應用在平面顯示器上最有潛力的技術。但是有機螢光小分子受到電子自旋的影響,最大內部量子效率的極限是25%。利用重原子金屬形成的錯合物,可以使單態和三重態能階混合產生高效率的電激磷光並應用在有機發光元件中。本篇文章中,我們將介紹磷光主發光體材料與紅、綠、藍磷光材料之發展與應用。

Electroluminance based on organic small molecule is one of the most promising technologies for flat panel displays. The quantum yield of current fluorescent dyes is limited to 25% due to the limited formation of singlet excited state. Heavy metal complexes can result in high-efficiency electrophosphorescence due to strong spin-orbit coupling leading to singlet-triplet state mixing, and hence they are attracted to apply in the fabrication of organic light-emitting devices (OLED). In this article, we detail the recent developments and applications of the red, green, blue materials and the host materials in electrophosphorescent OLEDs.
