High-efficiency pure-white organic light-emitting diodes (OLEDs) were fabricated using small polysilicic acid nanodot embedded polymeric hole-transporting layer. By incorporating the nanodot, the efficiency of a solution-processed phosphorescent white OLED was increased from 6.8 to 23.7lm/W, an improvement of 250%. 17.1lm/W was obtained while the same concept was applied on a mixed-host composed fluorescent white OLED.
