Abstract

A homoleptic iridium (iii) tris(pheny-limidazolinate) complex realizes a high EQE of 30%, a low turn-on voltage of 2.5 V, and a small efficiency roll-off in a blue organic light-emitting device (OLED). This device also shows high power efficiencies over 75 lm W(-1) and an ideal light distribution pattern at 100 cd m(-2).

摘要

一种同多面型铱（III）三（苯并咪唑基）配合物在蓝色有机发光器件（OLED）中实现了 30%的高光致发光量子效率、2.5 V 的低开启电压和较小的效率滚降。该器件在 100 cd m(-2)的亮度下还具有超过 75 lm W(-1)的高光功率效率和理想的配光模式。
