Abstract

Nanostructured SrO thin film of thickness 139 nm was deposited by chemical bath deposition technique onto glass substrates using SrCl2.6H2O and NaOH as cationic and anionic precursors without complexing agents. The X-ray diffraction studies revealed that, SrO thin film is nanocrystalline in nature with cubic structure. The surface morphology of the SrO film was investigated by means of field emission scanning electron microscopy. The optical studies showed that SrO film exhibits direct as well as indirect optical band gap energy. The electrical resistivity and activation energy of SrO thin film is found to be of the order of 106 Ω cm and 0.58eV respectively.
