ChemInform Abstract: Two New Non‐Centrosymmetric n = 3 Layered Dion—Jacobson Perovskites: Polar RbBi₂Ti₂NbO₁₀ and Nonpolar CsBi₂Ti₂TaO₁₀.

Abstract

Single crystals of CsBi2Ti2TaO10 (I) are prepared by solid state reaction of Cs2CO3, Bi2O3, TiO2, and Ta2O5 (Pt crucible, 1000 °C, 24 h, 30% yield).

A High Laser Damage Threshold and a Good Second-Harmonic Generation Response in a New Infrared NLO Material: LiSm3SiS7

“…Recently, numerous famous NLO crystals have been discovered and have effectively solved the generation of UV-visible light [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22]. However, for the mid-far infrared (IR) region (3-20 µm), outstanding IR NLO materials have been discovered less, and only a few (chalcopyrites AgGaS 2 , AgGaSe 2 , and ZnGeP 2 ) have been commercially applied [23][24][25].…”
