Abstract

Optically Transparent multilayer NiO/Ag and NiO/Al heat mirrors were prepared which allow the visible radiation to pass through it and reflect the Infrared radiations. NiO thin film were deposited by sol-gel spin coating technique, Ag and Al thin films were prepared by thermal evaporation. XRD analysis showed that the formation of cubic structure of NiO. The chemical analysis reveals that Ni2O3 phase also present along with the NiO phase. The transmittance spectra of NiO/Ag and NiO/Al coatings showed good transmittance in visible region while highly reflective in infrared region.XRD analysis of the film showed the formation of cubic structure of NiO. The chemical analysis showed that some peaks are belongs to other phase of the NiO. The transmittance spectra of multilayer of NiO/Ag and NiO/Al films are good transparent in visible region and reflect well in infrared region.
