摘要
Nitrogen-doped TiO2 nanoparticles with visible-light absorption properties were investigated with x-ray absorption and emission spectroscopy. The results indicate the substitution of nitrogen on the oxygen sites which are bonded to titanium atoms in the TiO2 host. The nitrogen dopant does not apparently change the crystal field nor the contribution of the O orbitals to the electronic structure of the TiO2 host, but alters slightly the Ti component of the electronic structure of the TiO2 host. Such a doping effect is likely to be the explanation for the visible-light absorption properties of the nitrogen-doped TiO2 nanoparticles.
