Two interesting non-centrosymmetric metal chalcogenides, Rb2Ag3Sb3S7 and Cs2Ag3Sb3S7, were synthesized by
an ionothermal approach. Crystals of compounds Rb2Ag3Sb3S7 and Cs2Ag3Sb3S7 possess isomorphic configuration, consisting of
two-dimensional (2D) anionic networks ∞[Ag3Sb3S7]2−, which are split by alkali-metal M+ cations. The band gaps are 2.11 and
2.02 eV for Rb2Ag3Sb3S7 and Cs2Ag3Sb3S7, respectively. Second-harmonic generation (SHG) studies revealed that Rb2Ag3Sb3S7
affords a powder SHG...[Show more]
