Zinc doped Tin oxide nanoparticles were synthesized by chemical precipitation method. The synthesized metal oxide nanoparticles were characterized by SEM, XRD, FT-IR, and UV-Visible respectively. The average crystallite size of pure and Zn-doped SnO2 nanoparticles was calculated from the X-ray diffraction (XRD) pattern. The results of FT-IR spectrum reveal the strong presence of SnO2 nanoparticles. The morphology and the particle size were studied using the scanning electron microscope (SEM). The optical property was studied by the UV–Visible absorption spectrum. The overall results suggest that the synthesized samples are suitable for various applications including for the development of solar cells and dye degradation.
