摘要	The polyacrylamide gel method combined with low temperature calcination technology have been used to synthesize the SrMoO4/SrWO4 micro/nano heterojunction phosphors with excellent photoluminescence properties. The effects of mass ratio of SrMoO4/SrWO4 on the phase structure, microstructure, charge state, photoluminescence performance and photocatalytic activity of SrMoO4/SrWO4 phosphors were systematically studied. Various characterization methods jointly confirmed that SrMoO4 and SrWO4 formed a special interface contact, generated a large number of oxygen vacancies, and then promoted the transfer and recombination of charge carriers, and further enhanced the photoluminescence properties of SrMoO4/SrWO4 micro/nano heterojunction phosphors. The SrMoO4/SrWO4 micro/nano heterojunction phosphors exhibits novel emission peak at 440 nm with the excitation wavelength of 310 nm and the ultraviolet intrinsic emission peak at 378 nm of SrMoO4. Photocatalytic experiments further confirmed that the SrMoO4/wt 5% SrWO4 micro/nano heterojunction phosphors have high charge transfer and recombination rates, demonstrating high photoluminescence properties for the SrMoO4/SrWO4 micro/nano heterojunction phosphors. This new idea provides a technical reference for the construction of heterojunction phosphor with special interface contact and its application in LED and laser fields. © 2021 Elsevier B.V.
