Characterization on the Microstructures and Optical Performances of TiO₂ Doped with Transition Metals

Abstract:

The structures and optical performances of TiO₂ doped with 4^th periodic transition metal ions were investigated in this paper. The characterization results of X-ray photoelectron spectroscopy and X-ray diffraction showed that the transition metal ions existed in oxidative states, and composites formed because of the reaction between doped metal ions and TiO₂. The absorption spectroscopy of TiO₂ doped with zinc was mainly in ultraviolet region, close to that of the pure TiO₂. While for TiO₂ doped with other transition metal ions including V, Cr, Mn, Fe, Co, Ni and Cu ions, the absorption spectroscopies covered ultraviolet region and visible light region, much broader than that of the pure TiO₂.
