Lighting consumes one-fifth of the electricity generated in the United States. Solid-state lighting offers tremendous potential to improve the situation – once major research challenges are overcome. The most promising technology is the organic light-emitting diode, or OLED. These multi-layered devices produce light by running an electrical current through a specially engineered host material into which light-producing phosphorescent molecules are embedded or "doped." The white light envisioned for large-scale applications, such as rooms and buildings, consists of red, green and blue light. read more
