“…For the design of high-quality materials, one of the strategies is to modify and improve the classic materials by chemical reactions, which can not only overcome the shortcomings of the original materials, but also obtain better performance. Polar crystal structures are always decent templates, which have attracted more and more attention, due to their unique characteristics. − Thereinto, boracite structure (a chemical formula of M 3 B 7 O 13 X, where M stands for a divalent metal cation) with a new functional building block (FBB) (B 7 O 18 ) gets our attention, which is a multifunctional family with ferroelectricity, ferroelasticity, NLO properties, and so on. − Based on the consideration of the DUV transparency, alkaline earth metal cations became our first select for M. Thus, Mg 3 B 7 O 13 Cl crystals were investigated, which exhibit a short DUV absorption cutoff (band gap of 7.96 eV), a moderate SHG response (NLO coefficient near to that of KDP), and the typical ferroelectricity . The unity of the DUV transparency, NLO and ferroelectric properties makes Mg 3 B 7 O 13 Cl crystal a promising DUV quasi-phase matching material.…”

Nonlinear optical crystals play important roles in modern laser science and technology. However, the design and growth of new nonlinear optical (NLO) materials is still a challenging issue for researchers. Due to the excellent performance of Mg 3 B 7 O 13 Cl crystal, we paid attention to the optimization of its structure, in order to find new NLO materials with favorable properties. Here, Zn 3 B 7 O 13 Cl crystals were obtained by a hightemperature solution method. Its structure was determined to be the trigonal symmetry with a polar space group of R3c, which is more highly symmetric than that of Mg 3 B 7 O 13 Cl (Pca2 1 ). The experimental and theoretical investigations demonstrated that the title compound exhibits a short absorption cutoff (band gap ∼6.53 eV), moderate SHG responses (2.2 times that of KDP at 1064 nm), and the improved birefringence, which results from the large distortion and anisotropy of borate groups and zinc polyhedrons. Therefore, the structural modification of Mg 3 B 7 O 13 Cl by zinc cations achieves a balance between the deep-ultraviolet transparency, the nonlinear optical effect, and the moderate birefringence, which is very significant for the design of practical NLO materials.

“…When these two crisscrosses are along the same direction, extinction will occur and the vision goes black. We can also get more information of the phase by observing the extinction angle with the experience gained in the study of traditional perovskite ferroelectric system, such as PZT and PMN‐PT [14] . Figure 4(b) presents the domain structure at the crossed P/A:0° at room temperature.…”

Molecular ferroelectric 3‐ammonioquinuclidinium‐NH4Cl3 (3‐AP‐NH4Cl3) crystals were prepared. DSC‐CP‐TG curves were studied and a small endothermic peak was discovered at 146 °C without obvious mass change. Dielectric properties were measured and a sharp peak was found at 146 °C in the dielectric constant versus temperature curve. Temperature‐dependent domain evolution was observed in situ by polarized light microscopy (PLM). The extinction‐variation temperature range agreed well with the phase transition temperature that takes place in the dielectric measurement. This result further confirmed a phase transition from ferroelectric phase to paraelectric phase. A schematic diagram is also established to clarify the temperature induced phase transition. The shape change of free energy curve caused by temperature may result in the phase transition.
