چکیده

V and La co-doped and undoped ZnO thin films were deposited on a glass substrate via the sol–gel method to investigate the structural, optical, and wettability of ZnO thin film by changing the V-doping concentration. Microstructure and water contact angles of the films were measured by SEM and contact angle goniometer, respectively. SEM studies revealed that the grain size and surface roughness of the film were changed by doping concentration. In addition, the contact angles were studied to find the possible effects of doping on the hydrophilicity of the film, indicating that the ZnO films were hydrophobic in nature. Finally, a good correlation was observed between the SEM micrographs and contact angle results, and the nature of ZnO film was found to be changed from hydrophobic to hydrophilic.
