This research work focus on the preparation and characterization of Aluminum doped Zinc oxide (AZO) nanoparticles by Microwave sintering technique. The nanostructure, morphology and optical properties of the synthesized AZO nanoparticles were characterized by X-ray Diffraction (XRD), Scanning Electron Microscope (SEM), Energy Dispersive X-ray (EDAX), Ultraviolet-Visible (VU-Vis) spectroscopy and Fourier Transform Infrared (FTIR) respectively. The XRD analysis exhibits that the AZO nanoparticles were in hexagonal wurtzite structure. The average crystallite size was estimated as 34.66 nm to 45.54 nm for 0.5. at.% - 1.5 at.% aluminum concentrations. The SEM micrographs showed the morpology of AZO nanoparticles. The presence of Al, Zn and O also were confirmed by EDAX analysis. The FTIR analysis exposes the composition of prepared AZO nanoparticles. The optical absorbance of 0.5 at.% - 1.5 at.% of aluminum doped nanoparticles was estimated between 354 nm and 357 nm. The prepared nanoparticles exhibit the transmittance between 88 % - 99.5 % in the visible region. The obtained energy band gap values of the prepared samples are in the range of 3.50 eV to 3.47 eV.
