Sol Gel Process

AbstractManganese zinc oxide semiconductor thin films have been deposited by sol-gel process on glass substrate which was characterized by means of X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX) and UV-Vis spectroscopy (UV-Vis). The as deposited thin films on glass are monophasic with good crystallinity and hexagonal wurtzite structure. In order to increase the photocatalytic efficiency of the zinc oxide coatings the authors optimized the sol-gel process and doped the coatings with manganese. By slightly doping the zinc oxide films with 2 at% manganese the photocatalytic performance is increased compared to pure zinc oxide semiconductor thin films. The photocatalytic performance of the manganese zinc oxide films was evaluated by the decomposition of a textile dye (C.I. Reactive Yellow 86) (RY86) with UV light irradiation. This investigation will give a new insight to understanding the industrial textile dye photodegradation in aquatic environment.

Background: In this work, CdS thin films were synthesized by sol-gel method (spin coating technique) on glass substrates to investigate the optical behavior of the film. Methods: Different substrate spin coating speeds of 2400, 3000, 3600 rpm and different Ni dopant concentrations of 0 wt.%, 2.5 wt.%, 5 wt.%) were investigated. The optical properties of thin films such as refraction index, extinction coefficient, dielectric constant and optical band gap energy of the layers were discussed using spectroscopic ellipsometry method in the wavelength range of 300 to 900 nm. Results: It can be deduced that substrate rotation speed and dopant concentration has influenced the optical properties of thin films. By decreasing rotation speed of the substrate which results in films with more thicknesses, more optical interferences were appeared in the results. Conclusion: The samples doped with Ni comparing to pure ones have had more optical band gap energy.
