The red-emitting phosphor [K<sub>0.8</sub>Y<sub>0.65</sub>Eu<sup>3+</sup><sub>0.08</sub>][Mo<sub>0.2</sub>W<sub>0.8</sub>O<sub>4</sub>] was produced by a solid-state method. Through XRD spectra, DTA-TG and photo-luminescent analysis, the possible reaction path and the emission mechanism of the phosphor were mentioned, and the partial Judd–Ofelt parameters and quantum efficiency of Eu<sup>3+</sup> <sup>5</sup>D<sub>0</sub> energy level were 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 light-emitting diode in the future.
