Résumé:
ZnO thin films have been prepared on glass substrates at various temperatures 150, 250, 350 and 450°C, using pneumatic spray pyrolysis technique in order to investigate the structural and optical properties of the films. The analysis of DRX diagrams shows that the deposits have a polycrystalline structure with (100), (101) and (002) textured orientation. Electro-optical properties depend on process parameters such as solution concentration and substrate temperature. The UV-Visible spectrophotometer of films confirmed that it is possible to obtain transparent ZnO thin films in the visible region with optical gap energy of approximately 3.2 eV
