In this study, we report the elaboration of vanadium-aluminium co-doped ZnO nanoparticles prepared by a sol-gel processing technique. Aluminium and vanadium doping concentrations of 1 at% and 10 at% respectively have been investigated. The obtained nanopowder was characterised by various techniques such as transmission electron microscopy (TEM), X-ray diffraction (XRD) and photoluminescence (PL) spectroscopy. After thermal treatment at 500°C in air, the powder with an average particle size of 30 nm presents a strong luminescence band in the visible range. The PL band energy position presents a small blue shift with the increase of measurement temperature. Different possible attributions of this emission band will be discussed. 274J. El Ghoul et al. S.
