Recently, non-centrosymmetric（NCS） Hg-based chalcogenides have garnered significant interest due to their strong second-harmonic-generation intensities(deff), making them attractive candidates for infrared nonlinear optical（IR-NLO） application. However, achieving both wide band gaps（Eg） and large phasematched deffsimultaneously in these materials remains a challenge due to their inherent constraints on each other. In this research, we have successfully obtained two quaternary NCS Hg-based chalcogenides, Rb2HgGe3S8and Cs2HgGe3S8, by implementing a bandgap engineering strategy that involves alkali metal introduction and Hg/Ge ratio regulation. Both compounds consist of 2D [Hg Ge3S8]2–anionic layers made of 1D [HgGeS6]6–chains and dimeric [Ge2S6]4–polyhedra arranged alternately, and the charge-balanced Rb+/Cs+cations located between these layers. Remarkably, Rb2HgGe3S8and Cs2HgGe3S8exhibit overall properties required for promising IR-NLO materials, including sufficient PM deff（0.55–0.70 × AgGaS2@2050 nm）, large Eg（3.27–3.41 e V）, giant laser-induced damage thresholds（17.4–19.7 ×AgGaS2@1064 nm）, broad optical transmission intervals（0.32–17.5 μm）, and suitable theoretical birefringence（0.069–0.086@2050 nm）. Furthermore, in-depth theoretical analysis reveals that the exceptional IRNLO performance is attributed to the synergy effects of distorted [HgS4] and [GeS4] tetrahedra. Our study provides a useful strategy for enhancing the Egand advancing Hg-based IR-NLO materials, which is expected to extended and implemented in other chalcogenide systems.
