Investigation on Structural, Surface Morphological and Dielectric Properties of Zn-doped SnO₂ Nanoparticles

Zinc doped Tin oxide (SnO₂) nanoparticles were prepared by co-precipitation method. The average crystallite size of pure and Zn-doped SnO₂ nanoparticles was calculated from the X-ray diffraction (XRD) pattern. The FT-IR spectrum indicated the strong presence of SnO₂ nanoparticles. The morphology and the particle size were studied using the scanning electron microscope (SEM) and transmission electron microscope (TEM). The particle size of the Zn-doped SnO₂nanoparticles was also analyzed, using the Dynamic Light Scattering (DLS) experiment. The optical properties were studied by the UV–Visible absorption spectrum. The dielectric properties of Zn-doped SnO₂ nanoparticles were studied at different frequencies and temperatures. The ac conductivity of Zn-doped SnO₂ nanoparticles was also studied.
