• Al-doped ZnO
• Structural properties
• Optical properties
• Homogeneous precipitation method

Al-doped ZnO (AZO) nanoparticles are prepared by the homogeneous precipitation method, which were characterized by X-ray diffraction, scanning electron microscope, ultraviolet and visible spectrophotometer and an infrared spectrometer. It is found that the AZO particles are of hexagonal wurtzite phase. With increase of Al doping, the particle size become smaller. A minimum diameter of 20 nm is obtained doped with 5 mol% Al. The band gap is found to broaden with increasing dopant concentration, and the ultraviolet absorption peak appeared blue shift. When doped with 5 mol% Al, the ultraviolet absorption rate and the visible light transmittance are 98% and 90%, respectively.
