Abstract
A light emitting structure includes a semiconductor light emitting device capable of emitting first light having a first peak wavelength, a luminescent material capable of emitting second light having a second peak wavelength disposed over the semiconductor light emitting device, and a photonic band gap material disposed between the light emitting device and the luminescent material. The photonic band gap material is capable of transmitting the first light and reflecting the second light, regardless of the angle of incidence of the first and second light.
