Solvothermal synthesis of raspberry-like YVO4:Eu nanoparticles in methanol-water system

YVO4:Eu nanoparticles with controllable size were successfully fabricated by the original solvothermal method at 300°C for 3 hours employing methanol-water solution. The effect of the solution pH on size and morphology of the YVO4:Eu particles was examined. SEM micrographs have revealed that the pow...
