Sr2MoO4 fluorescent powder was prepared by low-temperature combustion method and applied to WLED, and good luminous properties were obtained. In order to further optimize the performance of the fluorescent powder, we characterized it, including XRD, SEM, EDS, PL and other tests. The results showed that the photoluminescence intensity of Sr2MoO4 fluorescent powder was high, and the fluorescence spectrum had a wide emission spectrum band, which could match the emission spectrum of WLED and improve the light efficiency. Therefore, in practical applications, Sr2MoO4 fluorescent powder can be used as a potential WLED fluorescent material.【Keywords】WLED; rare earth strontium molybdate; fluorescent powder; low-temperature combustion method; luminous properties
