Solid-state synthesis and fluorescence properties of micron Bi2MoO6:Eu3+/C3N4 composite phosphors

The red emitting composite phosphors Bi2MoO6:Eu3+/C3N4 were prepared via a solid-state method and characterized by different techniques like XRD, SEM, FT-IR, Raman, UV-vis DRS and PL. The effects of reaction temperature and C3N4 amount on the structure and optical properties of Bi2MoO6 were studied in detail. The powder X-ray diffraction patterns showed that the crystal phase structure changed with the increase of temperature. Also, the introduction of C3N4 had a significant impact on photoluminescence properties, which provides a universal strategy for phosphors to improve luminescence performance.
