Abstract
The red-emitting phosphors [K0.8Y0.65Eu3+0.08][Mo0.2W0.8O4] were produced by solid-state method. Through XRD spectra, DTA-TG and photoluminescent analysis, the possible reaction path and the emission mechanism of the phosphor were mentioned and the partial J-O parameters and quantum efficiency of Eu3+5D0 energy level are calculated under 395 nm excitation. The results indicate that the red-emitting phosphor, of which the quantum efficiency is 13.43%, can become the potential applications for white LED in the future.
