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.
