Structural Analysis of Cu Doped TiO 2 Nanoparticles using Williamson-Hall Method

Abstract

Pure and doped Ti1-xCuxO2 nanoparticle is synthesized by co-precipitation technique successfully with nominal composite of x=0.0,0.01,0.02 and 0.03 at room temperature.The precursorswere further calcined at500 to 600◦C for 6hrs in furnace which results in the formation of different TiO2 phase compositions. The structural analysis carried out by XRD (Bruker D8 Cu-Kα1). X-ray peak broadening analysis was used to evaluate the crystalline sizes, the lattice parameters, number of unit cell per particle, c/aratioandVolume of unit cell. The Williamson Hall analysis is used to find grain size and Strain of prepared TiO2 nano particles. Crystalline TiO2 with a Tetragonal Anatase phase is confirmed by XRD results. The grain size of pure and Cu doped samples were found in the range of 10nm to 18nm. All the physical parameters of anatase tetragonal TiO2 nanoparticles were calculated more precisely using modified W-H plot a uniform deformation model (UDM). The results calculated were approximately similar with standard values. Keyword: TiO2; Co-precipitation; Particle Size; W-H analysis
