Production of ZnO and CdO-ZnO thin Films by Extraction–Pyrolytic Method

Characterization of ZnO Thin Films

ZnO is a strategic material for various photonic applications. We present our results on characterization of thin films of ZnO grown by sol-gel spin and RF sputtering methods. The characterization techniques involved ellipsometry, scanning electron microscopy with energy dispersive analysis, X-ray diffraction and scanning tunneling microscopy. Microstructural characterization of the films using...

Cathodoluminescence Properties of Zno Thin Films

Transparent conductive Nd-doped ZnO thin films

Transparent Nd-doped ZnO films with thickness in the range of 70 to 250 nm were grown by pulsed-laser deposition (PLD) on c-cut sapphire substrates at various oxygen pressures and substrate temperatures. A wide range of optical and electrical properties of the films were obtained and correlated to the composition and crystalline structure. The Nd-doped ZnO films are smooth, dense, and display t...

Ultraviolet detectors in thin sputtered ZnO films.

Sputtering of ZnO is a well-known technique.'9 The application of sputtered thin films of ZnO has mainly been as surface acoustic wave transducers. To our knowledge nobody has yet used these films as detectors for UV radiation. Measurements of the intensity of UV radiation, for example in medical applications in connection with UV irradiation of the skin, are very inaccurate due to the lack of ...

DMMP Sensing Performance of Undoped and Al Doped Nanocrystalline ZnO Thin Films Prepared by Ultrasonic Atomization and Pyrolysis Method

Highly textured undoped (pure) and Al doped ZnO nanocrystalline thin films prepared by ultrasonic atomization and pyrolysis method are reported in this paper. ZnCl2 water solution was converted into fine mist by ultrasonic atomizer (Gapusol 9001 RBI Meylan, France). The mist was pyrolyzed on the glass substrates in horizontal quartz reactor placed in furnace. The Structural and microstructural ...
