Simultaneously, these chiral compounds preserve 1D crystal structures to create strong free exciton, broad self-trapped exciton (STE), and discrete band energy levels, which facilitate the resonant enhancement of SHG and THG …
WebChiral complexes of R-FeNb and S-FeNb show second harmonic generation (SHG) due to their non-centrosymmetric structure. The I 2 1 3 space group provides second-order susceptibility tensor elements of χ xyz , χ yzx , and χ zxy , which contribute to SHG.

WebApr 1, 2024 · The difference in SHG intensity under right circularly polarized (RCP) and left circularly polarized (LCP) light excitations gives rise to a second harmonic generation-circular dichroism (SHG-CD) effect. Although natural chiral molecules can generate SHG-CD, the strength can hardly reach the requirement for practical applications [9]. Chiral ...
