Abstract:
A semiconductor light emitting device is combined with a wavelength converting material. The semiconductor light emitting device is configured to emit first light of a first peak wavelength. The wavelength converting material is configured to absorb at least a portion of the first light and emit second light of a second peak wavelength. In some embodiments, the first wavelength converting material is (Ba1-xSrx)2-y-0.5zSi5N8-zOz:Euy2+ where 0.2
