| Abstract: | Ni(in mode)doped TiO 2 nanoparticles were prepared by a sol_gel method with(C 4H 9O) 4Ti as raw material and nickel nitrate as doping agent and by deposition method using titanium sulfate and ammonium carbonate as raw material and nickel nitrate,cobalt nitrate hexahydrate,chromic nitrate and ammonium metavanadate as doping agent.Properties of the samples were characterized by means of TG_DTA,FTIR,SEM and PL.The experimental results show that different conditions of preparation influent greatly on the characterization. |
