Synthesis of YVO4 Nanoparticles with Controllable Morphologies by Solvothermal Method

YVO4 nanoparticles with various morphologies were tuned directly by hydrothermal treatment in different solutions, including pure water, potassium hydroxide solution, hydrazine hydrate, ethanolamine, triethylamine, and pyridine. X-ray diffraction (XRD), Raman, and transmission electron microscopy (TEM) were utilized to characterize the structure, morphology, and size of the products, which indicated that tetragonal phase YVO4 crystallites displaying rod-like, square, and olivary shapes were obtained. It was found that the selected solvents play an important role in modulating the morphology and confining the size of the obtained products.
