In this work, zinc stannate (Zn2SnO4) nanomaterials were synthesized as a composite system of zinc oxide and tin oxide by sol-gel via hydrolysis process for 60 hours. The effect of annealing temperature on the structural, optical and electrical performances of zinc stannate nanomaterials has been studied. XRD studies revealed that zinc stannate possess spinel cubic crystal structure and their growth in the preferred orientation (311) with characteristic temperature. The surface morphology of the zinc stannate nanomaterials were obtained by scanning electron microscope (SEM). EDAX and FTIR studies were employed to determine the chemical compositions and functional groups of the zinc stannate respectively. The optical properties of the hydrolysed zinc stannate were analysed by UV-visible and photoluminescence spectroscopy. UV-vis spectra were associated to the optical bandgap with a tunable range of 3.17-3.92 eV. PL spectra exhibit the stable broad blue-green emission around 400-600 nm with various excitation wavelengths. Complex impedance spectra reveal that the resistivity of the prepared zinc stannate nanomaterials is in the order of ~ 105 Ω Cm. Hence, zinc stannate is a promising candidate for DSSC applications.
