Abstract

SnO~2~ nanocrystalline thin films were prepared by a spray pyrolysis method on glass substrates at 375, 400, 425, 450 and 500 °C. Structural, optical and electrical properties of these films were studied by X‐ray diffraction, UV–visible and four‐probe methods. The change in electrical conductivity, band gap and optical transmittance was found to be a function of the change in lattice parameters Δ__a__ and Δ__c__ The samples prepared at 425 °C are found to have good figure of merit and maximum transmittance (96% at 550 nm).
