Alternative to Conventional Lighting - Efficient and Environmentally Friendly White Organic LED

Researchers in Hong Kong claim to have developed the highest power efficiency non-doped white organic light emitting device (WOLED) made using a single white-emitting material. They believe that their high purity, color stable device, surpasses existing WOLEDs and is a more efficient and environmentally friendly alternative to inorganic LEDs.

Optics and Photonics Plays an Important Role in Nano and Solar Technology

"Optics + Photonics is proceeding on the right track with its emphasis on nano and solar technologies, which are immensely important to our future," said Akhlesh Lakhtakia, Charles Godfrey Binder professor of engineering science and mechanics at Pennsylvania State University and editor-in-chief of SPIE's Journal of Nanophotonics. Lakhtakia continued, "But this emphasis on the nano and solar future has its feet firmly planted in the past glories and ongoing research in optics and photonics, a foundation from which all future technologies emerge."
