Growth of zno and al doped zno films by hydrothermal method

Zinc oxide is extensively used as UV light filters, gas sensors and as conductive electrodes in solar cells. For this purpose, extensive research is being carried out to increase the properties of Zinc Oxide and doping. Therefore, in this study; undoped ZnO and AZO films with different Al (%1, %3, %5) content were prepared by hydrothermal method on glass substrates. The influence of Al doping on the structural, surface and optical properties of ZnO films was investigated. On the other hand, as a parameter of hydrothermal method; temperature, time and molarite effects on the properties of the ZnO and AZO film were investigated. After the coating process, for characterization; X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), and absorption measurements were used. The XRD and SEM measurements showed that the films are covered well on the substrates and have hexagonal wurzite structure. With using the optical absorption measurements, the band gap values of the films were determined. Keywords: ZnO, AZO, Hydrothermal method, XRD, SEM, UV/VIS spectrophotometer.
