XRD SEM and CV characterization show that La~(3+) or Cd~(2+) doping changes the surface structure of TiO_2. UV-via absorption spectrum shows that the absorption band of doped TiO_2 film moves to longer wavelength.是什么意思_XRD SEM and CV characterization show that La~(3+) or Cd~(2+) doping changes the surface structure of TiO_2.
