Abstract
Metal chalcogenides are extensively studied as infrared second-order nonlinear optical (NLO) materials. Among the candidates, ones containing cations with lone-pair electrons in the structure have received great interest in view of the lone-pair electrons’ special contribution to the NLO property. Here, we revisit such a sulfide Sb6Sb6S17 and study its NLO property, which represents a novel structure-type of NLO material. It exhibits phase-matchable second-harmonic generation activity, and the powder sample shows a laser-induced damage threshold (LIDT) around 3.2 times that of AgGaS2 when both have the particle sizes of 75–110 μm. Its optical energy gap is measured to be 1.92 eV and the powder sample has a transparency range from 0.65 to 25 μm. The electronic structure and optical property calculations are also performed.
