Fluorine-containing borate crystal materials are particularly attractive due to their rich structural chemistry and excellent properties for optical applications. In this work, a new compound Ba3.75MgB7O14F2.5 has been synthesized through the high-temperature solution method. In the crystal structure of Ba3.75MgB7O14F2.5, the [B7O14] basic building unit and the [MgO3F3] octahedra are interconnected to create a complex three-dimensional network. The structural feature of the less commonly observed [B7O14] units is discussed, and it has been found that such units in Ba3.75MgB7O14F2.5 are most conducive to achieving large birefringence. In addition, Ba3.75MgB7O14F2.5 exhibits good thermal stability, a short ultraviolet cutoff of 203 nm, and large birefringence (0.081@546 nm), indicating its potential as a new UV birefringent crystal.

Two new alkaline-earth-metal fluoroiodate compounds, BaI2O5F2 and BaIO2F3, were successfully synthesized by replacing the O atoms in the iodates with F atoms via the hydrothermal method. They crystallize in centrosymmetric space groups P21/c and Cmca, respectively. Both compounds possess large birefringences (Δn) of 0.174 at 1064 nm for BaI2O5F2 and 0.133 at 1064 nm for BaIO2F3. Structurally, BaI2O5F2 has a large birefringence due to the highly polarizable [IO3F]2− with high anisotropic polarizability; for BaIO2F3, owing to the regulation of cationic polyhedra, the arrangement of [IO2F2]− anionic groups is well-ordered, and it exhibits large anisotropy. Also, both compounds exhibit a short UV cutoff edge, 230 and 234 nm, respectively. These results demonstrate that the two new alkaline-earth-metal fluoroiodate compounds will have potential applications as UV birefringent materials.

Birefringent crystals are particularly important in optical communication and laser industries. Herein, we report the synthesis, structures, optical properties, and theoretical analyses of an oxyborate birefringence material CdInO(BO 3 ). It has an interesting sandwich-like basic building unit (BBU) constructed by [CdO 4 ] 6− chains and [InO 4 ] 5− chains. CdInO(BO 3 ) possesses an experimental band gap of 3.65 eV and an ultraviolet (UV) cut-off edge about 295 nm. Moreover, it exhibits a large birefringence (0.136@1064 nm), which mainly originates from the parallel arrangement of the isolated [BO 3 ] groups. This discovery indicates that CdInO(BO 3 ) can be a promising birefringent material.

A new silicate fluoride, Mg2Pb2Si2O7F2, has been successfully synthesized using a high-temperature solution method. It crystallizes in the orthorhombic space group Pbcn (No. 60). Mg2Pb2Si2O7F2 is the first lead-containing alkali earth metal silicate fluoride. The optical characterization indicates that Mg2Pb2Si2O7F2 possesses a wide transparent window. To confirm the coordination environment of Si and its thermostability, infrared spectra and thermal behaviors were also analyzed. First-principles calculations were also implemented for a better understanding of the relationship between the structure of Mg2Pb2Si2O7F2 and its properties. Additionally, to further explore the structural novelty of Mg2Pb2Si2O7F2, its structure is compared with anionic structures of silicate fluorides with alkali metals, alkaline earth metals or lone pair metal cations. Interestingly, the results indicate that the isolated [Si2O7] dimer is rare among the above systems, which enriches the structural chemistry of silicate fluorides.

Birefringent crystals can modulate and detect the polarization of light, and have been widely used in the field of optoelectronic devices. The combination of a d10 transition metal cation and π-conjugated (H2C3N3O3)− group is a feasible approach for the synthesis of new crystal structures possessing large birefringence and short cutoff edges. Herein, a new hydroisocyanurate birefringent material Zn(H2C3N3O3)2·3H2O (ZHCY) was synthesized by a mild hydrothermal method. ZHCY featured a 2D layered ribbon structure constituted by coplanar π-conjugated (H2C3N3O3)− hydroisocyanurates, and displayed a wide band gap (5.24 eV) and a large birefringence (Δnexp ∼ 0.323, Δncal = 0.283 at 800 nm). Theoretical calculations revealed that its optical properties mainly originated from the π-conjugate coplanar (H2C3N3O3)− groups, which contribute to the enhancement of birefringence.

The chlorine barium nitrate Ba(NO3)Cl was synthesized, for the first time to the best of our knowledge, by using a mild hydrothermal method. Its structure was observed to feature an ABW-type topology (BaCl-ABW) framework, which can be considered as stacks of honeycomb-shaped sheets. Also, Ba(NO3)Cl crystals with dimensions of up to 2 × 1 × 0.5 mm3 were grown. Remarkably, Ba(NO3)Cl was found to exhibit a short UV cutoff edge (below 213 nm) and a markedly enhanced birefringence (Δn = 0.178 @ 1064 nm), about 19 times that of its parent phase BaCl2 (Δn = 0.009 @ 1064 nm). Theoretical calculations indicated that the birefringence enhancement mainly derived from the planar [NO3] triangles.

Fluorooxoborates are promising yet largely untapped crystal materials for linear and nonlinear optical applications. The introduction of a strong electronegative F atom into an oxyboron anionic group offers a virtually unlimited chance for structural engineering and ultimately purposeful tuning of the macroscopic optical properties of the crystal. Herein, a new mixed alkali/alkaline-earth fluorooxoborate, Na2BaB12O18F4, was synthesized in a closed system. Na2BaB12O18F4 features a [B6O11F2] fundamental building unit (FBB), which polymerizes into two new (first example) independent interpenetrating three-dimensional (3D) B–O/F anionic networks constructed entirely from BO3 and BO3F units. Based on optical characterizations and the first-principles calculations, Na2BaB12O18F4 exhibits a moderate birefringence (0.054 @ 1064 nm) and a short ultraviolet (UV) cutoff edge (below 190 nm). The successful synthesis and characterization of Na2BaB12O18F4 may speed up the subsequent discovery of other mixed alkali/alkaline-earth metal fluorooxoborates.

In modern optics, birefringent materials that can manipulate light polarization play important roles in lasers and information fields. The search for ultraviolet (UV) crystals with large birefringence is the focus of attention in the field of optical materials. In this work, we synthesized two birefringent crystals, C2H12N6C4O4·2H2O and Na2C4O4·3H2O, containing planar π-conjugated [C4O4]2– groups. Attributed to the large structural anisotropy and relatively ordered arrangement of the [C4O4]2– groups, C2H12N6C4O4·2H2O and Na2C4O4·3H2O possess large birefringence of 0.20–0.21 at 1064 nm. Meanwhile, they exhibit short ultraviolet cutoff edges at about 280–300 nm, corresponding to the large band gaps of 4.35 and 4.24 eV, respectively. Using structural analysis and first-principles calculations, the origins of such large birefringence are investigated and discussed. This work provides two potential UV birefringent crystals and prompts the search for novel birefringent materials.

Phosphates are another new family of exploring deep-ultraviolet nonlinear optical materials. As one material, the simpler the composition is the more favorable synthesis and application is. In this work, a simple alkaline earth metal phosphate β -Ba(PO 3 ) 2 was synthesized by high temperature solid phase method. It is worth mentioning that it has short cut-off edge (<190 nm) and relatively large birefringence (Δn = 0.032 @ 1064 nm) in phosphates and the optical anisotropy and birefringence can be enhanced by optimizing the basic anion arrangement. Combining with theoretical analysis, the relationship between structure and performance is further elaborated. In additional, thermal properties, linear optical and nonlinear optical properties for β -Ba(PO 3 ) 2 were also investigated.

Deep-ultraviolet (UV) nonlinear optical (NLO) crystals with excellent performances are of great importance in laser science and technology. However, to design and synthesize an ideal deep-UV NLO material with a balance between second harmonic generation (SHG) response and UV cut-off edge is still a huge challenge. Herein, a new oxy-borate BaYOBO 3 (BaYBO) was designed and synthesized by substituting Be 2+ with Y 3+ from Sr 2 Be 2 B 2 O 7 . The BaYBO features a stable three-dimensional framework and satisfies the property balance between a large SHG response (~2.6×KH 2 PO 4 (KDP)) and a short UV cut-off edge (<190 nm) as a promising deep-UV NLO candidate. The study of structure-property relationship indicates that the large SHG response of BaYBO is mainly attributed to the coplanar arrangement and large number density of BO 3 triangles. These results demonstrate that substituting Be 2+ with Y 3+ cations is also a feasible strategy for developing new deep-UV NLO crystals.

Herein, two new acentric borogermanates, namely, Ca2GeB2O7 and Ca1.78Cd0.22GeB2O7, were obtained by combining BO4 with a GeO4 tetrahedron. The structures of the isomeric Ca2GeB2O7 and Ca1.78Cd0.22GeB2O7 feature two-dimensional (2D) [GeB2O7] layers parallel to the ab plane in which a GeO4 tetrahedron corner is shared with four [B2O7] units; the divalent cations are filled in between layers. Ca2GeB2O7 and Ca1.78Cd0.22GeB2O7 display second-harmonic generation (SHG) intensity around 0.4 and 0.6 times that of KH2PO4 (KDP), respectively. Ca2GeB2O7 possesses a short UV absorption edge (about 194 nm). Thermal stability measurements show that Ca2GeB2O7 melts congruently at high temperatures, whereas Ca1.78Cd0.22GeB2O7 melts incongruently and becomes amorphous at high temperatures. Moreover, measurements of the optical properties as well as theoretical calculations of these two compounds were conducted.

The discovery of novel organic–inorganic hybrid nonlinear optical (NLO) crystal materials holds great potential in advancing laser science and technology as they offer a wide range of benefits including easy synthesis, structural versatility, and high hyperpolarizability. Herein, the integration of l-tartaric acid (L-C4H6O6) and ZnSO4 gave rise to two acentric Zn-based organic–inorganic hybrid crystals, namely, Zn2(H2O)2(C4H4O6)2·3H2O (Zn-LT) and Zn2(H2O)(C4H4O6)(C4H6O6)(SO4)·4H2O (Zn-LTS). They both feature layered structures constructed by [ZnO6] octahedron, l-C4H6O6/l-C4H4O62–, water molecule, or [SO4] tetrahedron. Interestingly, they possess moderate second-order NLO effects of 0.28 × KH2PO4 (Zn-LT) and 0.57 × KH2PO4 (Zn-LTS), large birefringence of 0.075 (Zn-LT) and 0.069 (Zn-LTS), suggesting that the introduction of [SO4] groups with intrinsically weak polarizability and weak optical anisotropy induces the enhancement of the NLO effect while without reducing birefringence much. In addition, both of them display UV cutoff edges near 210 nm, indicating their potential as NLO crystals applied in the UV and solar-blind region.
