Abstract

Nickel oxide(NiO)thin films were deposite donto glass substrates by the DC reactive magnetron sputteringtechnique.Theas-depositedfilmswerepost-annealedinairat450–500 1C for5h.The effect of anealingon the structural,microstructural,electrical and optical properties were studied by X-ray diffraction (XRD),atomicforcemicroscope(AFM),four-probe resistivity measurement and UV-vis spectrophotometer.XRD studies indicated cubic structure with a lattice parameter of 0.4193nm.The band gapofthefilmswasfoundtobe3.58eV.Fouriertransforminfrared(FTIR)studiesindicateda broad spectrumcenteredat451.6cm�1. Photoluminescencestudiesexhibitedroomtemperature emissionat440nm.Cyclicvoltammetrystudiesin1MKOHsolutionrevealedtheelectrochromicnature of theNiOfilmspreparedinthepresentstudy.
