Abstract

CsLnZnS3 (Ln = Gd, Dy) crystals are obtained by the interaction of metal sulfides in the cesium iodide melt. It is found that these compounds are isostructural, belong to the KCuZrS3 structure type, and crystallize in the space group Cmcm with the parameters a = 4.010(5) Å, b = 15.32(3) Å, c = 10.542(19) Å for CsGdZnS3 and a = 4.0106(3) Å, b = 15.2493(12) Å, c = 10.5978(8) Å for CsDyZnS3. The structures of these compounds consist of {LnS6} octahedra and {ZnS4} tetrahedra, which by sharing edges, form charged 2∞{LnZnS3} layers separated by Cs+ ions. Band gaps of these compounds are determined as 3.70 eV and 3.84 eV for CsGdZnS3 and CsDyZnS3 respectively.
