An Extended X-ray Absorption Fine-Structure Study Of The Rare-Earth Sites In A Neodymium Doped Glass.

(Full text available)
The local environment around the metal sites in a Nd doped aluminosilicate glass has been determined using extended x-ray absorption fine structure. Detailed fitting of the spectrum reveals an average Nd coordination of 4.5 +/- 1 oxygen atoms at 2.15 angstrom and 4.5 +/- 2 oxygen atoms at 2.44 angstrom; a second shell, containing silicon atoms, is centred at 3.7 angstrom. It is suggested that all the oxygen atoms are nonbridging.
