Study of nanostructured Al doped ZnO films. (July 2013) - Rahman, A.
Abstract : Electroless Al doped ZnO nanostructured thin films were deposited on soda lime glass in the present work. The wet deposited films were dried in air and subsequently annealed in a muffle furnace in air environment. The film deposited samples were characterised by field emission SEM/energy dispersive spectroscopy, X-ray diffraction and ultraviolet-visible spectrophotometer. Microstructure of the Al doped ZnO film is strongly affected by increasing the deposition time and annealing temperature. Surface and cross-sectional morphology of Al doped ZnO film exhibited the dense microstructure as compared to undoped ZnO films. X-ray analysis shows a (101) preferential growth in all the films. The optical properties of the films were analysed in the spectral range of 300–800 nm. The obtained samples are highly transparent with a visual transmittance of >80% at 450 nm.
