Abstract A seed layer-assisted chemical bath deposition (SCBD) method at low temperature has been developed to growth uniform and high crystal quality cuprous oxide (Cu2O) nanoparticles on transparent conductive/glass substrates. These films were grown on indium-doped tin oxide (ITO) as seed layer which deposited on glass substrates using magnetron sputtering-RF . The ITO seed annealing process by continuous beam (CW) of CO2 laser was used prior to growing the Cu2O nanoparticles. In this study, controlled synthesis of Cu2O films were investigated by controlling the growth temperature at 55, 60, 65, and 70 oC, respectively. The products of films were characterized in detail by using field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD). Optical properties of this Cu2O nanoparticles were examined UV-Vis spectroscopy. The study suggests synthesis route for developing high quality Cu2O nanoparticles using SCBD method for optical and electronic applications.

The present work deals with the preparation and characterization of cadmium sulfur (CdS) thin films. These films are prepared by chemical bath deposition on the well cleaned glass substrates. The thickness of the samples was measured by using profilometer DEKTAK, structural and optical properties were studied by X-ray diffraction analysis, and UV-visible spectrophotometry. The optical properties of the films have been investigated as a function of temperature. The band gap energy and Urbach energy were also investigated as a function of temperature. From the transmittance data analysis the direct band gap ranges from 2.21 eV to 2.34 eV. A dependence of band gap on temperature has been observed and the possible raisons are discussed. Transmission spectra indicates a high transmission coefficient (75 %). Structural analysis revealed that the films showed cubic structure, and the crystallite size decreased at a higher deposition temperature.

Silica-modified polyaniline (SM-PAni) were deposited on glass and platinum-coated glass substrates via oxidative polymerization. Zinc sulfide (ZnS) were grown on top of SM-PAni films by chemical bath deposition. The surface and optical characteristics were investigated. SEM micrographs revealed the formation of SM-PAni nanostructures and ZnS nanospheres. Increase in nanosphere sizes were observed when Pt-coated substrates were used. UV-Vis spectra showed that SM-PAni/ZnS nanocomposites grown on both substrates exhibit good absorbance in the visible and ultraviolet region which is a good indication for potential solar cell application. Better absorbance in the ultraviolet region was observed when Pt-coated substrates was used. Vibrational peaks observed in FTIR confirmed the presence of SM-PAni particles.

Thin Film Adhesion

In this work, chemical bath deposition (CBD) method is used to form zinc oxide (ZnO) thin film nanostructures. Three types of zinc (Zn) precursors, namely Zn (NO3)2, ZnSO4 and ZnCl2, were used and the deposition time in water bath were controlled for 20, 40 and 60 minutes at 85 °C respectively. The effect of seed layer, by using potassium permanganate (KMnO4) solution, on the formation of zinc oxide (ZnO) thin films on glass substrates has been determined. It was found that the presence of the seed layer promote better adhesion of the films which allows ZnO to form with a higher growth rate on the substrate with only little or no loss by precipitation in the solution. The enhancement of the thin film adhesion is due to the in situ nucleation centres formation of hydrated oxide colloids of Mn (O)OH, acting as metal ion binding centres on the glass substrates surface. Meanwhile, in the absence of a seed layer, only scattered ZnO deposits are formed on substrates. By varying the deposition time, ZnO nanostructures with different length and diameter can be formed.
