Abstract
structural slabs. They exhibit moderate responses ∼0.7/0.5/0.6 × AGS and the widest bandgaps among NLO chalcogenides containing independent Ag sites, suggesting that they may have high laser-induced damage thresholds, which is verified by the experimental 1.5/3/4 × AGS. This study not only opens a new system of NLO materials, but also provides a reliable design strategy for future NLO materials.
