Nanorystalline zinc oxide powders with atomic Aluminum to Zinc ratio varying between 0.1% and 20% were synthetized using a simple solgel method and annealed at different temperatures. The samples were characterized by X ray diffraction, Raman spectroscopy and SEM imaging. It is found that Aluminum doping induces a monotonous decrease in ZnO grain size for annealing temperatures of 700°C and beyond. No such effect was observed below 500°C. furthermore, peaks associated with the ZnAl2O4 spinel phase were observed at high doping concentrations on both the X ray and infrared spectral.
