Photocatalytic, spectroscopic and transport properties of lanthanide-doped TiO2 nanocrystals

The photocatalytic properties of the anatase form of nanocrystalline TiO2 doped with lanthanide ions (Eu3+, Sm3+ and Er3+), obtained by a sol-gel preparation method, are studied by means of the degradation of methylene blue. It is observed that the presence of Sm3+ ion as a dopant significantly impr...
