Characterization of SnO₂ Nanoparticles Prepared by Two Different Wet Chemistry Methods

Abstract:

Effects of synthesis techniques, namely sol gel method and direct growth method on the nanostructural and optical properties of SnO₂ have been investigated. The XRD results confirmed that both samples are single phase SnO₂. The crystallite size of SnO₂ prepared by sol-gel and direct growth method were approximately 10 nm and 15 nm respectively. The FE-SEM micrographs displayed that SnO₂ nanoparticles prepared by sol gel method exhibited a round shape with approximate particle size of 10 nm while the direct growth method produced SnO₂ nanorod with length and width of 570 nm and 55 nm respectively. The direct E_g for both SnO₂ nanospheres and nanorods are 3.98 eV and 3.94 eV respectively, Due to quantum confinement effect, both nanomaterials exhibited strong blue shift compared to bulk material with E_g of 3.6 eV.
