Structural and optical properties of zinc oxide doped by V2O5 synthesized by solid-state reaction
2016
Abstract Vanadium doped zinc oxide with different vanadium concentration were synthesized by conventional solid state reaction. The structural and optical properties of ZnO: V 2 O 5 pellets were studied by using a panalytic diffraktometer (X'pert) with Cu–K radiation, the UV–visible spectrophotometer and photoluminescence (PL). X-ray diffraction (XRD) show that all the samples have a wurtzite structure and grow mainly in the (101) orientation, we show also the presence of dominated phase Zn 3 (VO 4 ) 2 , Optical studied indicate a decrease in optical band gap energy, and photoluminescence (PL) spectra showed a strong visible emission band, energy position and intensity of this emission depends on the temperature measurement. The activate energy Ea has been fitted and studied using Arunis equation.
