BaB2S4: An Efficient and Air-Stable Thioborate as Infrared Nonlinear Optical Material with High Laser Damage Threshold

“…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 ) …”

Novel ternary Zintl phosphide halides Ba3P5X (X = Cl, Br) with 1D helical phosphorus chains: synthesis, crystal and electronic structure

“…[16][17][18][19][20] Recently discovered pnictide halides and pnictohalides, such as A 2 As 7 X (A = Ba, Sr, Eu; X = Cl, Br, I) or W 6 PCl 17 , are considered unique low-dimensional semiconductors with promising tunability that may lead to the discovery of promising electronic and spintronic materials. 20,21 Our research group is interested in advancing novel heteroanionic compounds that are characterized by distinct charge transfer, aiming to develop narrow-gap semiconducting materials suitable for energy applications. Within this domain, polar intermetallic Zintl phases are known for their abundant chemical compositions, variability of crystal structures, and wide range of physical properties.…”

“…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.…”
