Ce-doped titanium oxide nanoparticles were investigated in the paper. The surface structures of undoped and Ce-doped TiO 2 nanoparticles were observed by scanning tunneling microscopy (STM). The experimental results of scanning tunneling spectroscopy (STS) show that the surface electronic structures of TiO 2 nanoparticles are modified by introducing new electronic states in the surface...
Doping with transition metal ions in TiO2 has been found effective to modify the electronic structure of TiO2 nanoparticles. Application of synchrotron radiation photoelectron spectroscopy (SRPES) to Nd-doped TiO2 nanoparticles revealed that there existed different peak positions and structure with different doping concentration in the valence band spectra. From the onset of valence band spectrum,...
