Title: Polar oxysulfide for nonlinear optical applications

Abstract

Single crystals of a new noncentrosymmetric polar oxysulfide SrZn₂S₂O (s.g. Pmn2₁) grown in a eutectic KF-KCl flux with unusual wurtzite-like slabs consisting of close-packed corrugated double layers of ZnS3O tetrahedra vertically separated from each other by Sr atoms and methods of making same.
