Abstract

L3-edge Extended X-ray Absorption Fine Structure (EXAFS) studies have been carried out on a praseodymium gallate glass (Pr3Ga5O12) prepared by aerodynamic levitation and laser heating. The short range ordering around the rare-earth has been obtained by combined technique including molecular dynamics simulation (MD). The results give an average PrO coordination number of 6.68(2) and a mean GaO coordination number of 4.29(2). A good agreement between the experimental data and the simple molecular dynamics simulations give rising a glass network of a PrO polyhedral structure and a predominant GaO4 tetrahedral network in this glass.
