Synthesis and characterization of GdVO4 nanoparticles by a malic acid-assisted sol-gel method
GdVO4 powders were synthesized by a sol-gel method using malic acid as a chelating agent, followed by calcinations at 300-700 °C for 3 h. The products characterized by FTIR, XRD, SEM and TEM, revealed that purity, crystallinity and particle sizes of tetragonal GdVO4 nanoparticles increased with incr...
