Abstract
We report intense green luminescence upon blue light excitation in -activated prepared by high temperature solid state reaction with nominal composition of . It is observed that the material phase gradually converts from to followed by improved luminescent properties with increasing . The two phosphors both emit with a maximum at . Significantly, shows a more intense excitation band in the blue centered at . Upon excitation, the integrated emission intensity of is 1.3 times stronger and nearly the same as phosphors. Attempts to understand the origins of the intense luminescence are presented on the basis of diffuse reflection spectra and fluorescence decays of in comparison with related phosphors. The present results suggest that could be a promising green emitting phosphor for excitation by blue light emitting diodes.
