Abstract: Nanoparticles are recent existence interesting for their remarkable optical properties and application in optical devices. Many methods have been used for the preparation of nanoparticles. TiO2 nanoparticles have been synthesised successfully by simple chemical rout method. The synthesised material was characterised by X-ray diffraction (XRD) and ultraviolet-visible (UV-Vis) spectroscopy techniques. The UV-Vis and XRD were used to study optical and structural properties of the synthesised TiO2 nanoparticles respectively. Optical absorption study in the wavelength range between 200-700 nm reveals that strong absorbance peak was found in UV-Vis region. Furthermore, visible energy band was almost transparent for the materials. The optimum value of optical conductivity for TiO2 nanoparticles was found to be 59.5 × 105 S−1.

Keywords: TiO2 nanoparticles; optical conductivity; UV-Vis spectroscopy; synthesis; titanium dioxide; nanotechnology; ultraviolet-visible spectroscopy; optical absorption.
