Abstract

Transparent semiconducting Al-doped ZnO thin films were prepared on silicon substrates by spray pyrolysis method followed by in air annealing at 450°C. Zinc acetate dehydrate, 2-methoxyethanol and aluminum nitrate were used as a starting material, a solvent and a dopant source, respectively. X-ray diffraction patterns show that annealing process improves the crystallinity of the Al doped ZnO thin films .The mechanism of blue-green luminescence of AZO thin film are analyzed. Energy-dispersive X-rays (EDX) were used to analysis the composition of Al doped ZnO films. The morphology of the AZO thin films is studied by atomic force microscopy and FE-SEM analysis. Average diameter of some also obtained nanorods is ~60 nm.

Key Words   
Spray pyrolysis, Al doped ZnO, Nanorods; photoluminescence, X-ray diffraction, morphology properties
