A photonic structure for "white" light generation by phosphors under the excitation of a LED. The photonic structure mounts the LED and an optically transparent matrix having dispersed therein phosphors which will emit light under the excitation of the radiation of the LED. The transparent matrix may...http://www.google.es/patents/US6734465?utm_source=gb-gplus-sharePatente US6734465 - Nanocrystalline based phosphors and photonic structures for solid state lighting
