摘要：

YVO4:Dy3+ phosphor powders were synthesized by using the hydrothermal method under different pH conditions. The crystallization, surface morphology, lattice vibration, optical properties, luminescent mechanism and influencing factors of the obtained YVO4:Dy3+ phosphor powders were carefully studied and analyzed in detail. All of the YVO4:Dy3+ phosphor powders had tetragonal structures, and the pH value had a significant impact on the surface morphology, structure and optical properties of the synthesized samples. Strong acidic and alkali environments were favorable for the crystallization of YVO4:Dy(3+)phosphor powders, and the YVO4:Dy3+ phosphor powders synthesized under strong alkali environments had the best luminescent properties.
