X-ray photoelectron spectroscopy (XPS) and ultraviolet photoelectron spectroscopy (UPS) study show that the SnO2 and SnO2:F are Sn2+ dominated in the formation of SnO2 structure. The SnO2:F thin film is mainly the formation of metallic fluoride. The UPS study confirms the density of states of SnO2:F is higher than SnO2. The work function, valence band maximum and surface potentials of SnO2 (SnO2:F) are estimated from UPS spectra and are 3.9 eV (3.7 eV), 3.7 V (3.5 eV) and 7.6 eV (7.2 eV), respectively. Electrical conductivity and M–H hysteresis loop show SnO2:F have higher conductivity as well as magnetization. [ABSTRACT FROM AUTHOR]
