We report on hybrid films based on ZnO/organic dye prepared by electrodeposition using tetrasulfonated copper phthalocyanines (TS-CuPc) and Eosin-Y (EoY). Both the morphology and porosity of hybrid ZnO films are highly dependent on the type of dyes used in the synthesis. High photosensitivity was observed for ZnO/EoY films, while a very weak photoresponse was obtained for ZnO/TS-CuPc films. Des...

     Zinc Oxide (ZnO) nanorods and titanium dioxide (TiO2) nanostructures thin films were prepared onto glass substrates by the chemical bath deposition (CBD) method. The ZnO was structured as nanorods (NRs) while TiO2 was formed as nanoflowers plate as confirmed by Field-Emission Scanning Electron Microscope (FESEM) images. The ZnO/Fe3O4 and TiO2/Fe3O4 nanostructures thin films were prepared v...

Nanostructured ZnO thin films have been deposited using a successive chemical solution deposi method. The structural, morphological, electrical and sensing properties of the films were studied different concentrations of Al-dopant and were analyzed as a function of rapid photothermal proces temperatures. The films were investigated by X-ray diffraction, scanning electron microscopy, en dispersi...

We report the photoelectrochemical (PEC) performance of textured porous ZnO and CdX-coated ZnO films (X = S, Se). Porous ZnO films were grown with a platelike morphology on F-doped SnO(2) (FTO) substrates. The growth of ZnO films involves a two-step procedure. In the first step, we electrochemically grew simonkolleite (Zn(5)(OH)(8)Cl(2)·H(2)O) plate films. Annealing of the simonkolleite at 450 ...

In this review paper, a critical analysis was carried out to investigate the effect of cathodic potential, bath temperature, time and nature of substrates on the ZnO thin films synthesized by electrodeposition technique. XRD patterns of the various deposited films were studied to examine the structural characteristics of the Nanostructured ZnO thin films. From the XRD patterns of the different ...

Monolayer Cu₂S and ZnO, and three kinds of complex films, Cu₂S/ZnO, ZnO/Cu₂S, and ZnO/Cu₂S/ZnO, were deposited on glass substrates by means of radio frequency (RF) magnetron sputtering device. The impact of the thickness of ZnO and Cu₂S on the whole transmittance, conductivity, and photocatalysis was investigated. The optical and electrical properties of the multilayer were studied by optical s...

background & objectives: nanotechnology is one of great important part of technology. nanoparticles can be used in different applications for industrial, medical, military and personal use. the objectives of this study were preparation of polystyrene/zno nanocomposite films via a simple method and investigation of antibacterial activity of them. methods: polystyrene /zno nanoparticle (ps/n...

We investigated the influence of low-concentration indium (In) doping on the chemical and structural properties of solution-processed zinc oxide (ZnO) films and the electrical characteristics of bottom-gate/top-contact In-doped ZnO thin-film transistors (TFTs). The thermogravimetry and differential scanning calorimetry analysis results showed that thermal annealing at 400 °C for 40 min produces...

ZnO thin films were prepared by RF magnetron sputtering method on SiO2/Si(111) substrate at different ratio of Ar/O2, which were annealed at different annealing temperatures to improve the films’ quality. The effects of the ratio of Ar/O2 and annealing treatment on the ZnO films’ properties were discussed. The crystal structures and surface morphologies of ZnO thin films were characterized by X...

Zinc oxide films have been formed from thermally evaporated zinc films on polished and textured silicon wafers after heat treatment at temperatures between 400-900°C for 10min in oxygen ambient. These ZnO films show crystalline structure and the values of their refractive index are found to increase slightly from 1.85 for films annealed at 400°C to 2.05 for the films annealed at 900°C. The film...
