Abstract
A light emitting device comprising a photonic crystal structure having a crystal structure in which nanospheres are densely arranged in a 3D manner, wherein the nanospheres have phosphors excited by an excitation source to emit light of a wavelength longer than a pump photon of the excitation source, wherein the photonic crystal structure has at least a photonic bandgap (PBG) along a specific crystal orientation, and wherein the wavelength of the pump photon overlaps a photonic bandedge region.
