Local structure investigation of oxide ion and proton defects in Ge-apatites by pair distribution function analysis

In this communication we provide a direct insight into the local structure and defects of oxygen excess Ge-apatites, in both dry and deuterated states, by means of pair distribution function analysis. © 2011 The Royal Society of Chemistry.We acknowledge the support of the INSTM-Regione Lombardia Project ‘‘PICASSO’’.Peer Reviewe
