Abstract
⺠Cobalt doping results in the increase in d-spacing and shifting of XRD peak position. ⺠Decrease in photoluminescence intensity of TiO2 after doping indicates inhibition of electron-hole recombination. ⺠Concentration quenching effect results in decrease in visible emission intensity ratio. ⺠Excitation peaks related to oxygen defects and Co2+ are observed in photoluminescence excitation spectra. ⺠Cobalt doped TiO2 has longer decay time compared to undoped TiO2.
