Résumé : |
In this work, MgO-ZnO thin films were deposited on galas substrate (450°C) by pneumatic technique. The effects of PH solution in the range of ((2.6; 5.0; 7.0 and 7.9 of Ph) were successfully investigated. MgO-ZnO thin films were observed in high crystallinity with a hexagonal wurtzite structure with a strong preferential, the maximum value of crystallite size 42.12 nm is attained of deposit MgO-ZnO thin film at 450 °C with 5 of PH. The optical transmission spectra showed all the sprayed MgO-ZnO thin films are transparency within the visible wavelength region. The band gap of MgO-ZnO thin films increases from 2.53 to 3.18 eV as the PH increases, The Urbach energy values decreased as the PH increased from 820 to 305 meV |
