Abstract:

Present study focused on the concentration effect of dopant on structural and optical properties of host material. Ti1-XCoXO2 for X=0.0, 0.025, 0.05, 0.075 nanocrystalline powder were synthesized using sol-gel method. Structural analysis were done by Xray diffraction (XRD) pattern, which confirmed the phase of synthesized nanoparticles corresponds to tetragonal anatase phase of TiO2. Also, extra peaks related any type of impurity is not observed in XRD pattern. The average crystalline size evaluated using Scherer’s formula was found to be from 45 nm to 29 nm. Crystalline size and strain also calculated using Williamson–Hall analysis. Band gap decreases with doping and further increases with doping concentration.
