Synthesis and characterization of GdVO4 nanostructures by a tartaric acid-assisted sol-gel method

GdVO4 nanoparticles were prepared by a sol-gel method employing tartaric acid as a chelating agent. Effects of calcination temperature and mole ratio of total metal ions to tartaric acid on the products were investigated. The products, characterized by XRD, FESEM and TEM, were tetragonal GdVO4 nanop...
