Optimizing the optical properties of ZnO nanoparticles with Al doping

This paper reports on the structural and optical properties of Al with different doping concentrations on ZnO nanoparticles prepared through Sol-Gel method. The XRD results revealed the wurtzite structure of ZnO without any secondary phase related to Al. The absorption spectrum of the sample exhibited an absorption in UV region and the Photoluminescence properties of Al doped ZnO were studied.
