Effect of Thickness on the Electronic Transitions of NiO Thin Films Prepared by Chemical Spray Prolysis

Abstract

Attended thin films of nickel oxide with different thickness on glass bases using thermochemical decomposition method, where he was studying the impact of thickness to nickel oxide on the electronic transitions of the energy gap.Absorbance was calculated within the range of wavelengths (900-300) and different thickness nm(140,180,240,280,330), as results showed that the absorbance less increase wavelength and all nickel oxide membranes while increasing absorbance increase the thickness of the membrane and the optical energy gap of the thin membranes under increasing thickness.
