Synthesis and Characterization of Alkaline-Earth Indium Sulfides

Abstract

In the course of studies of the AIn2S4 (A = Ca, Sr, Ba) system, a number of sulfides with metal stoichiometries near, but not necessarily equal to, 1:2 were encountered, including the new phases Ca1.2In1.9S4 and Sr0.9In2. 1S4. Indexed X-ray powder diffraction patterns of Ca3.3In6.5S13 (C Ca1.0In2.0S4. 0 ), Sr0.9In2.1S4, SrIn2S4, and BaIn2S4 are reported. All compounds have been grown as crystals from AC12-KC1 (A = Ca, Sr,Ba) fluxes. X-ray powder diffraction data indicate that this compound is isostructural with the previously reported phases Ca3.1In6.6S13 ( Ca1.0In2.0s4.0 ),Sn2.5In7S13 ( Sn0.8In2.2S4.0 ), and Pb3In6.67S13 ( Pb0.9In2.1S4.0 ). Observed X-ray powder diffraction data for crystals of a new compound, Ca1.2In1.9S4, are reported. Keywords: Ternary indium sulfides, LWIR-transmitting compounds, Crystal structure.
