Zusammenfassung:New combinations of semi-conductor devices in conjunction with optically active materials are set forth herein. In particular, light emitting semiconductors fashioned as diodes from indium gallium nitride construction are combined with high-performance optically active Langasite La3GasSi0i4 crystalline materials. When Langasite is properly doped, it will respond to the light output emissions of the diode by absorbing high energy photons therefrom and reemitting light of longer wavelengths. High-energy short wavelength light mixes with the longer wavelengths light to produce a broad spectrum which may be perceived by human observers as white light. Langasite, a relatively new material, enjoying great utility in frequency control and stabilization schemes has heretofore never been used in combination with optical emission systems.
