In the present work, nanoparticles of tin oxide (SnO2) annealed at temperatures of 400 °C, 500 °C, and 600 °C were prepared via solid-state reaction method. Structural and optical properties of prepared SnO2 nanoparticles were analyzed by X-ray diffractometer (XRD), scanning electron microscope (SEM), elemental study was performed by energy-dispersive X-ray spectroscopy (EDAX), Fourier transform infrared spectroscopy (FTIR), dynamic light scattering (DLS) and ultraviolet-visible (UV-Vis) absorption characterizing techniques. The X-ray diffraction pattern confirms the pure tetragonal rutile structure of tin oxide nanoparticles without any impurity phase. SEM images depict the formation of nanorods at all annealing temperatures of 400 °C, 500 °C, and 600 °C while EDAX analysis confirms the presence of Sn and O without any impurities. UV-Vis absorption spectra show that the band gap of prepared tin oxide nanoparticles decreases initially from 3.44 eV at 400 °C to 3.03 eV at 500 °C and further increases to 3.39 eV at 600 °C. FTIR spectrum confirms the presence of O–Sn–O bond along with one unwanted absorption peak.
