Abstract
OLED devices based on hexaphenylsilole (HPS) have been fabricated. These devices emit very bright greenish-blue light, up to 55880 cd/m2 at 16 V. Emission starts at 2.6 V, and reaches 100-cd/m2 and 10790-cd/m2 at 5 V and 10 V respectively. The maximum electroluminescence (EL) efficiency and power efficiency are 20-cd/A and 12.8-lm/W, respectively. The maximum external quantum efficiency is 7%.
