چکیده انگلیسی
Vanadium doped zinc oxide with different vanadium concentration were synthesized by conventional solid state reaction. The structural and optical properties of ZnO: V2O5 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 Zn3 (VO4)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.
