These compounds display good water resistance, wide infrared transparent region (0.42–17 µm), high laser-induced damage thresholds (4.5–6 × AgGaS2), and strong phase-matchable second harmonic generation (SHG) response close to AgGaS2. The mixed-anion chalcohalide groups serving as functional building units in NLO materials are studied for the first time and proven to be very effective. This work opens a new avenue for new NLO material design to achieve the balance between strong SHG efficiency and large bandgap.
