ACdCO₃F (A = K and Rb): new noncentrosymmetric materials with remarkably strong second-harmonic generation (SHG) responses enhanced via π-interaction

Abstract

The remarkably large SHG efficiency of KCdCO3F originates from enhancement via interatomic interactions between the s and p states of Cd2+ and the π-conjugated groups of the [CO3]2− unit.

Cs3VO(O2)2CO3: an exceptionally thermostable carbonatoperoxovanadate with an extremely large second-harmonic generation response

“…The title compound exhibits an extremely strong SHG response of ca. 23.0 times that of KDP, almost 7 times that of KSrCO 3 F, which is the largest among those of all the NLO carbonates, including CsPbCO 3 F (13 × KDP),32 RbCdCO 3 F (9 × KDP),53 and K 4 Eu 2 (CO 3 ) 3 F 4 (8 × KDP),54 reported to date. In addition, as seen in Fig.…”

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].…”

In situ Alkylation of 4,4′‐Vinylenedipyridine for Inorganic‐Organic Iodides/Iodidomercurates

“…Hence, the spectra of 1 are discussed in details as a representative. The peak at 3429 cm –1 is characteristic for water molecules, which may be due to the adsorbed surface‐H 2 O . The weak band at 3026 cm –1 is attributed to the C–H stretching vibrations of the methyl groups in 1 .…”
