摘要：

Soft-X-ray absorption spectroscopy was used to identify the electronic and crystal structure of titanium dioxide in nanocrystalline form prepared by gas condensation. High energy resolution spectra of the Ti 2p absorption edge revealed detailed spectral features identical to those from titanium in anatase. Based on the Ti 2p and O Is absorption spectra, we estimated that the Ti is in +4 valence state and the crystal field splitting of nanocrystal TiO2 is approximately 2.1 eV, slightly smaller than that of bulk TiO2.
