Description

The project aims to extend organic light emitting technology into a new product platform for general lighting and design lighting for household. The major technical obstacles that must be tackled for lighting include lifetime, output intensity, and tunable color temperatures of the devices. To achieve the goal, the team at CityU plans to utiiize unique properties of nanostructural materials to fabricate high-efficiency and long-lifetime White-emitting organic light-emitting devices (WOLEDs) by exploiting the technologies in triplet emission, stable emitters, optical coupling, stack cells, low operating voltage materials and structures, etc. We target at delivering practical WOLED with power efficiency greater than 20 1m/W and that of incandescent light sources. It is expected that within the next 10-15 years, OLED will replace the bulk of conventional light sources because of their advantages in longer lifetime, lower power consumption, potential of flexibility, and environmental friendliness (no mercury). The team at CityU already has an outstanding track record in the field of OLED and is equipped with a comprehensive set of OLED infrastructure and facilities. The proposed project will buttress the lighting infrastructure and technology base in Hong Kong and China.
