本文使用高温固相法，制备钼酸盐作为基质的荧光粉样品Sr0.7Ca0.16MoO4∶0.07Eu3+0.07A+(A=Na+,K+,Li+)，对荧光粉样品进行XRD和荧光光谱光学性能进行测定。研究结果表明，在900 ℃高温烧结8 h得到样品Sr0.7Ca0.16MoO4∶0.07Eu3+0.07A+(A=Na+,K+,Li+)。以615 nm作为监测波长，在330~540 nm处的激发峰中，394 nm、464 nm处的峰群中分别属于Eu3+的7F0→5D6、7F0→5D2跃迁。在394 nm和464 nm激发下Sr0.7Ca0.16MoO4∶0.07Eu3+0.07A+(A=Na+,K+,Li+)的发射光谱中，其主峰处于615 nm，是Eu3+通过5D0→7F2能级跃迁红光发射形成的。计算出CIE色坐标，并与美国国家电视标准委员会的标准值(x=0.670，y=0.330)进行对比，得出样品性能的优劣程度。综上所述，Sr0.7Ca0.16MoO4∶0.07Eu3+0.07A+(A=Na+,K+,Li+)是一种性能很好的红色荧光粉，可以应用于白光LED领域中。

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.
