Bi4O5I2 exhibits an extremely high second harmonic generation response and enhanced photocatalytic activity. The multifunction of Bi4O5I2 is mainly resulting from the dipole moment of the stereochemical activity of Bi 6s lone pairs.

Heterocyclic Structure

ABSTRACTNew noncentrosymmetric compounds having both electron-accepting and electron-donating substituents on a conjugated, aromatic heterocyclic structure were synthesized and their spectroscopic, thermal, and solubility properties were determined. D.C. electric field-induced second harmonic generation (EFISH) experiments were performed to provide values of the second-order nonlinear optical susceptibility/dipole moment product βμ. Long alkyl substituents were required in heterocycle-containing compounds for sufficient solubility to conduct EFISH analysis. 2,4-Dinitro-substitution on these imine-linked materials gave the highest βμ in the series.

Nonlinear Optical Effect

In order to investigate the doping effect of Ba 2 NaNb 5 O 15 by rare-earth ions, single crystals of stoichiometric BNN, Gd-doped BNN, and Nd-doped BNN were synthesized. The measurements were carried out for second harmonic generation (SHG), microscopic observation on {001}, and for dielectric property of these materials. The considerable effects by the doping were found for the SHG. The doping effect was investigated from the point of view of the theory of electro-optical and nonlinear optical effect on oxygen octahedral ferroelectrics, and from that of domain structure. Microscopic observation proved that the refractive index fluctuation causes several SHG phase matching conditions.

Novel visible-light responded aluminosilicophosphate-5 (SAPO-5)/g-C3N4 composite has been easily constructed by thermal polymerization for the mixture of SAPO-5, NH4Cl, and dicyandiamide. The photocatalytic activity of SAPO-5/g-C3N4 is evaluated by degrading RhB (30 mg/L) under visible light illumination (λ > 420 nm). The effects of SAPO-5 incorporation proportion and initial RhB concentration on the photocatalytic performance have been discussed in detail. The optimized SAPO-5/g-C3N4 composite shows promising degradation efficiency which is 40.6% higher than that of pure g-C3N4. The degradation rate improves from 0.007 min−1 to 0.022 min−1, which is a comparable photocatalytic performance compared with other g-C3N4-based heterojunctions for dye degradation. The migration of photo-induced electrons from g-C3N4 to the Al site of SAPO-5 should promote the photo-induced electron-hole pairs separation rate of g-C3N4 efficiently. Furthermore, the redox reactions for RhB degradation occur on the photo-induced holes in the g-C3N4 and Al sites in SAPO-5, respectively. This achievement not only improves the photocatalytic activity of g-C3N4 efficiently, but also broadens the application of SAPOs in the photocatalytic field.
