Synthesis and characterisation of Sb-doped ZrO_2 and TiO_2 nanoparticles

摘要

The present study aims at the synthesis and structural characterisation of Sb-doped titania and zirconia nanoparticles using a modified precipitation synthesis method. The produced nanoparticles were characterised using various techniques such as UV-Visible spectroscopy, Scanning electron microscopy, Transmission electron microscopy and Dynamic light scattering. The crystallite sizes were obtained to be <20 nm for Sb-doped ZrO_(2)and <10 nm for Sb-Doped TiO_(2)which was very evident from the Transmission electron microscope images. The hydrodynamic sizes in the range of 100 nm using Dynamic light scattering method were also evaluated for the assessment for biological application. The optical band gap was found out to be 3.21 eV for Sb-Doped TiO_(2)and 3.87 eV for Sb-doped ZrO_(2).
