We have investigated the core level and photoinduced Pb Auger transition regions of Pb2P2S6 , a member of the M2P2X6 chalcogenophosphate family using the x-ray photoemission spectroscopy. The XPS core level spectra show single peak structures for the Pb, P and S core levels in agreement with crystallographic data. The combined analysis of the Pb 4f 7/2 core level and the Pb N6 O45 O45 Auger transition has allowed us to deduce the modified Auger parameter for Pb in Pb2P2S6 obtaining in this way information on the Pb-S bond in this compound.

Abstract
We have investigated the core level and photoinduced Pb Auger transition regions of Pb2P2S6 , a member of the M2P2X6 chalcogenophosphate family using the x-ray photoemission spectroscopy. The XPS core level spectra show single peak structures for the Pb, P and S core levels in agreement with crystallographic data. The combined analysis of the Pb 4f 7/2 core level and the Pb N6 O45 O45 Auger transition has allowed us to deduce the modified Auger parameter for Pb in Pb2P2S6 obtaining in this way information on the Pb-S bond in this compound.File in questo prodotto:
