Abstract

In this contribution, ZnO nanoparticles and vanadium doped ZnO were synthesized by wet chemical and wet incipient method, respectively. ZnO nanoparticles were heated at 650 and 750Â°C for 3h in air and then characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive (EDX) analysis and photoluminescence (PL). The XRD patterns showed that the ZnO samples have a wurtzite structure (hexagonal phase) and vanadium doped is in V2O5 crystalline structure. Their structural characteristics and physical properties were investigated and compared. XRD and SEM data show that the size of nanoparticles increased from 24.3 to 32.6 nm when the annealing temperature was increased. Also, the results indicate that increasing the degree of crystalline improved the physical properties of the nanoparticles.
