Molybdate-based phosphor sample Sr0.7Ca0.16MoO4∶0.07Eu3+0.07A+(A=Na+,K+,Li+) was prepared by high-temperature solid-phase method. The phosphor samples were investigated by XRD and fluorescence spectra. The sample Sr0.7Ca0.16MoO4∶0.07Eu3+0.07A+(A=Na+, K+, Li+) was sintered at 900 ℃ for 8 h. With 615 nm as the monitoring wavelength, in the excitation peak at 330-540 nm, the peak groups at 394 nm and 464 nm belong to Eu3+ transitions of 7F0→5D6 and 7F0→5D2, respectively. Under the excitation of 394 nm and 464 nm, the main peak in the emission spectrum of Sr0.7Ca0.16MoO4∶0.07Eu3+0.07A+(A=Na+, K+, Li+) is located at 615 nm, which is the Eu3+ transition of 5D0→7F2 energy level. The calculated CIE (Commission International del, Eclairage) color coordinates formed by the red light emission, close to the standard values (x=0.670, y=0.330) of the National Television System Committee. In summary, Sr0.7Ca0.16MoO4∶0.07Eu3+0.07A+(A=Na+, K+, Li+) is a red phosphor with good performance and can be used in white LEDs.
