Preparation and characterization of aluminum doped zinc oxide (AZO) nanorods

Abstract

Aluminum doped Zinc Oxide (AZO) nanorods with 1at.% aluminum content were prepared by Sol-gel spin coating technique. The structural and topographical properties are studied using X-Ray Diffraction (XRD) technique and Atomic Force Microscopy (AFM), respectively. Higher intensity Zinc Oxide (ZnO) peak (002) is observed in 1at.% aluminum doped nanorod with 50 s spin coated sample underwent 300°C of annealing temperature. Morphologic, compositional and crystallographic information of the samples are predicted using Transmission Electron Microscopy (TEM), the 600 nm long nanorod with an aspect ratio of 10 is obtained for 20 s and 50 s spin coating time.
