The strong mutual coupling of and even the opposite change in the key parameters, such as the band gap (Eg) and second‐order harmonic generation (SHG), leads to the extreme scarcity in high‐performance IR nonlinear optical (NLO) chalcogenides. Herein, we report 8 new sulfides, Na2Ba[(AgxNa1−x)2Sn2S7...
