Efficient red-emitting phosphor for near-ultraviolet-based solid-state lighting

Eu(3+) ion activated Y(2)MoO(6) synthesized by the sol-gel method had been investigated as an alternative red-emitting phosphor for solid-state lighting. Excitation spectra, emission spectra, and decay curves were measured to characterize the luminescent properties. The phosphor shows efficient absorption of near-ultraviolet (NUV) light, and it also exhibits excellent performance in emission intensity and color purity compared with the commercial phosphor in current use. This red-emitting material may be applied as a promising red component for the NUV excited white diode.
