BASF and Siemens' Osram lighting unit have developed a white organic light-emitting diode prototype that they call a "major step on the way toward commercial OLED lighting." The prototype, which incorporates BASF semiconductor materials, generates a relatively high 60 lumens/W and retains its white color at different levels of light intensity. In such devices, white light is produced by combining materials that emit blue, red, and green light. BASF says a remaining challenge is developing more stable blue-light-emitting materials.
