“…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.

“…In subsequent works we will report the studies carried out on the Fe 1 5 Zn 1 5 B 7 O 13 Cl boracites with regard to their primary properties, i.e., ferroelectricity, ferroelasticity, ferromagnetism and ferrotoroidicity. 5 In a previous work on the domain structure of Mn 3 B 7 O 13 X and Zn 3 B 7 O 13 X (where X = Cl, Br or I) boracites, 6 11 and then to a trigonal phase with point group 3m at 480 K. 12 Phase transitions accompanied by a change of the point-group symmetry are generally called ferroic. 13 A ferroic crystal contains two or more possible orientation states or domains; under a suitably chosen driving force the domain walls (i.e., the intermediate regions between domains) move, switching the crystal from one domain to another.…”

New iron-zinc chlorine single crystals of Fe1.5Zn1.5B7O13Cl boracite were grown by chemical transport reactions in closed quartz ampoules, at a temperature of 1173 K. The crystal structure was characterized by X-ray powder diffraction (XRD) using the Rietveld refinement method and belongs to the trigonal/rombohedral system with space group R3c (No. 161). The cell parameters were a = 8.5726(1) angstroms, c = 21.0116(4) angstroms, V = 1337.26(3) angstroms3 and Z = 6. The refinement successfully proceeded and ended with sound merit figure values chi2 = 2.25, R(B) = 6.12%. Chemical analysis was performed with X-ray energy dispersive spectroscopy (EDS) and X-ray fluorescence (XRF). Ferroelectric nano and micro reoriented domains were found in this material using polarizing optical microscopy (PLM), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The examination by TEM showed that in the trigonal/rombohedral system of Fe1.5Zn1.5B7O13Cl nanodomain structures exist. Thin (50-100 nm) mostly planar domains parallel to (100) were frequently observed in Fe1.5Zn1.5B7O13Cl boracite.
