[A₃X][Ga₃PS₈] (A = K, Rb; X = Cl, Br): promising IR non-linear optical materials exhibiting concurrently strong second-harmonic generation and high laser induced damage thresholds.

ABSTRACT: Mid-far infrared (IR) non-linear optical (NLO) materials are of great importance in military and civil fields. However, commercial IR-NLO crystals (such as AgGaS₂, AgGaSe₂ and ZnGeP₂) do not currently satisfy the requirements of large second-harmonic generation (SHG) and high laser induced damage thresholds (LIDTs), which seriously limits their practical applications. Herein, we have developed a new series of salt-inclusion chalcogenides, [A₃X][Ga₃PS₈] (A = K, Rb; X = Cl, Br), which are constructed from alternate stacking of adamantane-like [Ga₃PS₁₀]^6- cluster layers and cationic [A₃X]²⁺ salt layers. Importantly, they display both large SHG responses of several-fold and
