Abstract
Techniques and optically excited light-emitting devices based on phosphors are provided to use phosphor materials which absorb excitation light to emit visible light and include a composite phosphor material including two or more different transition metal compounds that, under optical excitation of the excitation light, emit visible light at spectrally close but different spectral wavelengths or bands that spectrally overlap to produce a desired color.
