Abstract

Al Doped and undoped ZnO nanoparticles were synthesized at room temperature followed by quenching at relatively low temperature for size control. The XRD patterns of Al doped nanoparticles were similar to those of undoped nanoparticles, indicating the presence of Al ions at substitutional sites and that the AZO retained the crystal structure of ZnO. The presence of Al ions was confirmed by the XPS study. UV Visible spectroscopy reveals blue shift which in turn indicates an increase in the band gap.
