A PHOTOEMISSION-STUDY OF SB-DOPED TIO2

Abstract:

The influence of Sb-doping on the electronic structure of TiO2 (rutile) has been investigated by core and valence level photoemission spectroscopy, supplemented by high resolution electron microscopy, SQUID magnetometry and infrared reflectance spectroscopy. Pronounced segregation of Sb to polycrystalline TiO2 surfaces is evident from core level XPS, with a surface Sb concentration that increases only weakly with nominal Sb doping level in the range between 1% and 10%. Segregated Sb ions may ...
