Phosphor-free White LEDs for More Efficient Backlight Applications Developed by UCSB

A new LED manufacture method which does not require phosphor to make white semipolar LED was published by a research team of UCSB with Shuji Nakamura, Nobel winner and LED pioneer, as a co-author. The result was published in Optics Express. White light emitting LEDs are usually made from blue LEDs combining yellow phosphor. But phosphor converted white LEDs usually suffer energy loss and reduced thermal stability. Phosphor-free LEDs, however, are rather difficult to fabricate but the UCSB team proposed an easier method to achieve efficient and polari...
