Abstract:
Concurrently achieving suitable second harmonic generation (SHG) effect and high laser-induced damage threshold (LIDT) is challenging for infrared nonlinear optical (NLO) materials. Here, a series of pentanary infrared NLO materials CsMIIIMIVSnSe6 (MIII = Ga, In; MIV = Si, Ge) have been obtained by a three-in-one strategy, viz. three kinds of elements (MIII, MIV, and Sn) in one position, which is first adopted to design NLO materials. Their three-dimensional structures are constructed by the MQ4 (M denotes MIII, MIV, and Sn) tetrahedral units. They exhibit promising hybrid NLO properties, witnessed by their moderate/large SHG effects of 0.52, 0.98, 1.05, and 1.12 × AgGaS2, and high powder LIDT values of 6.9, 4.1, 8.1, and 5.4 × AgGaS2, respectively. These NLO properties are well verified by the DFT calculation results. The three-in-one strategy of designing high-performance infrared NLO materials will stimulate more investigations in this field.

Stereoisomerism
Isomers are different chemical species that have the same chemical formula.
Transition metal complexes often exist as geometric isomers, in which the same atoms are connected through the same types of bonds but with differences in their orientation in space. Coordination complexes with two different ligands in the cis and trans positions from a ligand of interest form isomers. For example, the octahedral [Co(NH3)4Cl2]+ ion has two isomers (Figure 1) In the cis...
