“…Meanwhile, chalcogenides, owing to its wide optical transmission range and strong NLO response, are wildly researched for IR NLO materials. Recently, in view of the performance drawbacks (low laser damage threshold (LDT) and harmful two photon absorption) of commercial IR NLO materials, − it is urgent to explore new excellent IR NLO materials − with suitable balance between wide bandgap ( E g ≥ 3.0 eV) and large second harmonic generation (SHG) effect (NLO coefficient d ij ≥ 0.5 × benchmark AgGaS 2 ) …”
N onlinear optical (NLO) crystals are of great importance in producing coherent ultraviolet−visible (UV−vis), deep-UV (DUV), or infrared (IR) light sources for civil and military applications by frequency-conversion technology. 1−23 Borates are widely applied as short-wave NLO materials because of their large bandgaps and high laser damage threshold that originate from strongly covalent B−O bonds in [BO 3 ] 3− and [BO 4 ] 5− anionic groups, such as β-BaB 2 O 4 , 1 LiB 3 O 5 , 2 KBe 2 BO 3 F 2 , 3 etc.; unfortunately, they cannot be used in the IR region because of absorption resulting from their B− O vibration modes which limits the infrared transmission. Meanwhile, chalcogenides, 6 owing to its wide optical transmission range and strong NLO response, are wildly researched for IR NLO materials. Recently, in view of the performance drawbacks (low laser damage threshold (LDT) and harmful two photon absorption) of commercial IR NLO materials, 24−26 it is urgent to explore new excellent IR NLO materials 27−33 with suitable balance between wide bandgap (E g ≥ 3.0 eV) and large second harmonic generation (SHG) effect (NLO coefficient d ij ≥ 0.5 × benchmark AgGaS 2 ). 34

“…Several A 2 Pn 7 X phases crystallize in the chiral space group P2 1 3a desirable prerequisite for the materials requiring chiral control and enantioselectivity. 20 As these phosphide and arsenide halides do not have inversion symmetry, they can be used for application in second harmonic generation and ferroelectricity. 29 Among pnictogens, phosphorous exhibits remarkable homoatomic bonding formation capability, which results in the constant discovery of novel phosphorus allotropes, like recently reported P 11 , 30 structurally diverse polyanions, such as infinite 1 1 P − chains in BaP 2 , 31 oligomeric [P 9 ] units in Ba 5 P 9 , or 0D [P 7 ] 3− clusters in A 2 Pn 7 X.…”
