Annotation Nanocomposite ZnO : SnO2 and pervoskite ZnSnO3 nanoparticles were synthesized with different volume ratios [40 : 60 (wt %), 50 : 50 (wt %), 60 : 40 (wt %), 70 : 30 (wt %) and 30 : 70 (wt %) respectively] have been deposited by spray pyrolysis technique on glass substrate using an aqueous solution of Zinc chloride (0.1 M) and Stannic chloride (0.1 M) at a substrate temperature 400  5 C. The structural, surface morphological and optical characterizations of the as-prepared samples were carried out using XRD, SEM, TEM and UV-VIS spectrophotometer, respectively. The XRD result showed nanostructured pervoskite thin films of ZnSnO3 and composite of ZnO : SnO2. The volume ratio of zinc chloride and stannic chloride when varied, the particle size was found increasing where as particle shape changed from circular to hexagonal. The X-ray diffraction spectroscopy results indicated that all the samples had the good crystallinity. The ultraviolet-visible absorption spectra showed increased band gap for the samples as compare to the reported values. With the transmission electron microscope, we got some morphology information and evidence to support the UV and XRD analysis results.
