This article reports on VIS-active composite thin films based on zinc oxide (ZnO) and copper sulfide (CuxS) deposited using robotic spray pyrolysis deposition (SPD) for the study of the optical and photocatalytic properties. The first step involves the SPD deposition of a CuxS layer onto the glass substrate at 300°C. The second step consists of the deposition of a ZnO layer onto the CuxS layer to form glass/CuxS-ZnO composites that were further annealed at 400°C. The development of the composite thin films was confirmed by XRD and EDX analyses. The band gap energy ( E g ) of the bare ZnO thin films decreased from 3.15 eV to an activation energy value of 2.8 eV after the deposition of the ZnO thin layer onto the CuxS layer and from 2.8 to 2.08 eV after annealing the CuxS-ZnO composite at 400°C. The UV-VIS irradiation (5.5% of UV, G = 55   W / m 2 ) of a 10 ppm methylene blue solution was used to investigate the photocatalytic properties of the CuxS-ZnO composites. The annealed CuxS-ZnO thin films at 400°C demonstrates better photocatalytic activity compared to CuxS-ZnO composites deposited at 300°C. The enhanced photocatalytic efficiency of the annealed CuxS-ZnO thin films may be the result of the diode structure and the increased crystallinity that prevent the electron-hole recombination.

AbstractBismuth-doped tin oxide films have been deposited using a new spray-pyrolysis deposition system. Among the properties are the possibility of depositing thin films over very large areas with good uniformity and the relatively small cost compared with other types of deposition systems. The apparatus is divided in two major parts, the aerosol chamber and the deposition chamber. The deposition chamber consists of a flat rotating hot plate that can house substrates up to 18 cm in diameter. Deposition temperature ranges from 290 °C to 350 °C. The SEM pictures show a phase transition from amorphous to polycrystalline which also strongly affects the transport properties of the film. The high values of the surface resistivity obtained are consistent with those ones required to develop an analog grey scale ferroelectric liquid crystal display. The sample shows a 20% uniformity in the value of surface resistivity over an area of 140 cm2, and the results obtained until now show a satisfactory reproducibility. Bismuth and Tin concentration versus deposition temperature have been determined by ICP mass spectrometry. Our work is supported by the ESPRIT project “PROFELICITA”.
