XANES Pb L-III spectra of mixed-valence compound: minium, Pb3O4

摘要

Mixed-valence compound Pb3O4 (minium) has been studied using X-ray absorption near-edge structure (XANES) spectroscopy and DFT calculations. In spite of the presence of two valence states of lead Pb(II) and Pb(IV), the XANES spectrum of studied system is corresponding to apparently unified, an intermediate valence state of Pb. The explanation is related to the basics of XANES spectroscopy. (c) 2005 Elsevier B.V. All rights reserved.
