In this work, we have prepared undoped and vanadium doped ZnO nanopowders by sol–gel method. The treated powder at 500 °C has an average particle size of 25 nm. Pellets have been prepared at sintered temperature of 900 °C in atmospheric furnace. The characterization of the obtained pellets has been made by the X-ray diffraction, the UV–visible spectrophotometer, and cathodoluminescence (CL). The XRD...
