Optical Properties of Al Doped Zinc Oxide Nanorods Thin Film Deposited by Immersion Technique

Article Preview

Abstract:

We investigated the effect of immersion time on optical, electrical properties and surface morphology of nanostructured Aluminium (Al) doped Zinc Oxide (ZnO) thin films prepared by immersion technique. UV-Vis-NIR spectra indicate that the transmittance of the samples decrease with immersion time. Electrical properties study reveals the nanostructured Al doped ZnO thin film at 1 hr shows the lowest resistivity compared to other samples. Surface morphology results as characterized by scanning electron microscope (SEM) show that the Al doped ZnO nanorods quantity increased with immersion time.
