Abstract

The method of neutron diffraction with isomorphic substitution was used to measure the structure of the rare-earth chalcogenide glasses
(R2X3)0:07(Ga2X3)0:33(GeX2)0:60 with R = La or Ce and X = S or Se. X-ray diffraction was also used to measure the structure of the sulphide glass. The results are consistent with networks that are built from GeX4 and GaX4 tetrahedra, and give R-S and R-Se coordination numbers of 8.0(2) and 8.5(4), respectively. The minimum nearest-neighbour R-R distance associated with rare-earth clustering is discussed.
