Nanostructured Aluminium (Al) doped zinc oxide (ZnO) has been prepared using sol-gel spin-coating method. The annealing temperature was varied and the effect on the surface characteristic of ZnO thin film was studied. The surface topography and morphology of the thin films were characterised using X-ray Diffractometer (XRD), Atomic Force Microscopy (AFM) and Field Emission Scanning Electron Microscopy...
Layer-by-layer ZnO nanoparticles thin films were deposited using sol-gel spin coating technique. Zinc acetate dihydrate, 2-methoxyethanol and monoethanolamine were used in the ZnO solution. Different numbers of film layers were employed to study their effects to the physical, electrical and optical properties of the thin films. XRD patterns showed that the films were single crystalline with highly...
This paper reports on the preparation of nano-structured of MgxZn1-xO thin films by sol-gel spin coating method which will be used as a template layer to grow carbon nanotubes. The MgxZn1-xO films were deposited on Pt/Si (100) substrates. In this work, we focused on the effect of sol aging and Mg content on the film structure and resistivity. Sols with Mg content of x = 0.1, 0.3 and 0.5 were subjected...
Zinc Oxide (ZnO) thin films were deposited on a glass substrate by sol-gel process dip-coating method. Zinc acetate dehydrate Zn(O2 CCH3)2(H2O)2 are used as a starting material while 2-methoxyethanol (C3H8O2) and monoethanolamine (MEA) are used as a solvent and stabilizer. The molar ratio of zinc acetate dihydrate to MEA is 1:1. The molarity of the solution and pre-heating temperature were kept constant...
Titanium dioxide in the anatase phase has been synthesized by the sol-gel method. Then, the solution was deposited onto glass substrate using spin coating technique. These thin films are then annealed at a temperature ranged from 350°C to 550°C. The optical and topology of the thin film was characterized using UV-VIS and AFM. Based on the readings from UV-VIS spectroscopy, it is found that transmittance...
