Uv-Visible Study of Optically Transparent Nickel Oxide Thin Film Prepared By Chemical Spray Pyrolysis Technique

Characterization of an Optically Transparent Nickel Oxide Thin Film

Abstract

Highly transparent nickel oxide (NiO) thin film was depositedonto the glass substrates by using simple and economic Chemical spray pyrolysistechnique. Aqueous solution of nickel chloride () was used as a precursor solution. Theprecursor solution of molarity 0.5 M was sprayed through glass nozzle onpre-heated glass substrate. The substrate temperature was kept constant at 400°C during the film deposition. Optical property of prepared film was studied bymeans of UV-visible spectrophotometer in the spectral range 300-900 Ǻ. Opticalstudy revealed the excellent optical transparency of NiO film. Average transparencyabove 80% has been observed in the entire visible region which offered a strongcandidature for thin film based coating applications.
