- Abstract
This paper presents the study conducted on the synthesis and the investigations of Zinc stannate nanoparticles. Hydrothermal method was used for the synthesis. Characterizations for the products obtained were done with the help of powder X-ray diffraction, scanning electron microscopy, transmission electron microscopy, UV-Vis absorption spectroscopy. The X-ray powder diffraction result was used to characterize the morphology and also it confirmed the well crystalline wurtzite structure. Typical electron microscopic investigations of SEM and TEM were used to study the morphology and the particle size. The formation of ZnSnO nanoparticles and their particle size were confirmed by the TEM analysis. The optical properties were analyzed using UV-Vis absorption and PL spectrum. The FT-IR spectrum confirmed the presence of ZnSnO nanoparticles. The dielectric properties, e.g. dielectric constant, dielectric loss, and AC conductivity of the ZnSnO nanoparticles, were measured and studied as a function of frequency and temperature. Those nanoparticles exhibit quantum size effects of the optical absorption spectrum. The influence of reaction conditions on the growth of ZnSnO nanoparticles demonstrates that high precursor concentration and high reaction temperature (≥200 °C) is a favorable growth in the formation of zinc stannate.
