Silver iodomolybdates are under investigation in order to define a transport model for AgI-based oxide glasses. In this paper we report a preliminary EXAFS study on a glass of composition 0.66AgI:0.33Ag2MoO4. The EXAFS Fourier transform shows two peaks that are attributed to the coordination with oxygen (Ag-O distance 2.38(1) angstroms, coordination number 1.5(3)) and iodine (Ag-I distance 2.830(5) angstroms, coordination number 1.5(3)), respectively. The present coordination numbers confirm our previous 109Ag NMR results.

Abstract

Silver iodomolybdates are under investigation in order to define a transport model for AgI-based oxide glasses. In this paper we report a preliminary EXAFS study on a glass of composition 0.66AgI:0.33Ag2MoO4. The EXAFS Fourier transform shows two peaks that are attributed to the coordination with oxygen (Ag-O distance 2.38(1) angstroms, coordination number 1.5(3)) and iodine (Ag-I distance 2.830(5) angstroms, coordination number 1.5(3)), respectively. The present coordination numbers confirm our previous 109Ag NMR results.
