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.

A challenging topic for tetrahedra-based deep-ultraviolet (deep-UV, wavelength λ < 200 nm) birefringence crystals is how to generate both large birefringence and high deep-UV transmittance. Edge-sharing tetrahedra can induce large structural distortion and thus could produce strong optical polarization anisotropy to realize the challenging topic, but edge-sharing tetrahedra frequently require extreme synthesis conditions to overcome large repulsion interaction between tetrahedra. Herein, under mild hydrothermal conditions, an α-Be3(H2O)2(PO4)2 crystal with edge-sharing BeO4 and its polymorph β-Be3(H2O)2(PO4)2 with common corner-sharing BeO4 were synthesized, both featuring a three-dimensional stable structure constructed by BeO4, BeO2(H2O)2, and PO4 tetrahedral units. Remarkably, α-Be3(H2O)2(PO4)2 manifests superior birefringence of 0.101 and high deep-UV transmittance of 167 nm, with the largest birefringent quality factor (BQF) of 0.75 among the known tetrahedra-based deep-UV materials. By contrast, β-Be3(H2O)2(PO4)2 manifests a small birefringence of 0.019 and 160 nm deep-UV transmittance, with only a mediocre BQF of 0.15. Further, computational investigations reveal that edge-sharing BeO4 makes a dominant contribution to the great birefringence. This study could push the synthesis of edge-sharing-tetrahedra materials and offers an alternative strategy toward designing high-performance tetrahedra-based deep-UV birefringence 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.

Chameleons can rapidly modify their coloration by manipulating the arrangement of iridophores encompassing guanine crystals in their dermis, which enables incident light to undergo birefringence. Various biomaterials have been designed to mimic the arrangement of guanine crystals, yet instances of synthesizing bottom-up structures with anisotropy for optical functionality remain rare. In this study, we report a novel two-step gas diffusion method for in-situ synthesis of CaCO 3 (Vaterite) within a hydrogel to fabricate a bio-photonic film displaying birefringence interference colors. This strategy enables the successful fabrication of an inorganic–organic photonic film with superior mechanical properties and flexibility, resulting in high transparency, superior toughness, and adjustable optical anisotropy. Through a combination of experiment and simulation results, we elucidated the critical role played by shape factor (distribution) and structural factor (particle size) in producing transmitted interference colors. Finally, the birefringent photonic films prepared using the dot-plate method can function as optical patterns accurately representing the “on”/“off” state within a binary system. This system offers high spatial resolution, excellent repeatability, and precise controllability of optical properties, making it applicable in fields such as information encryption and decrytion. Our study has successfully synthesized photonic material with anisotropic structure though in-situ method while elucidating the underlying mechanism governing their ability to generate transmission interference colors, thus opening up new avenues for transparent flexible polarized optics, imperceptible wearable devices, and advanced information encryption.

Enhancement of birefringence is significant since the birefringent materials can create and control polarized light and be used extensively in various advanced optical systems. By optimizing the arrangement of [SbS3] units with stereo-chemical active lone pair electrons, a new quaternary thioantimonate LiSrSbS3 with a large birefringence has been successfully synthesized by a high temperature solid-state reaction method. LiSrSbS3 crystallizes in the monoclinic space group of P21/c. In the structure, the isolated infinite [LiS4] chains and zigzag [SrS6] chains are alternately connected with each other to compose a three-dimensional (3D) framework, and the isolated pyramid [SbS3] units are located between them. To analyze the source of large birefringence, the electronic structure and optical properties of LiSrSbS3 were further investigated by the first-principles method, and the results show that the optimized arrangement [SbS3] trigonal pyramid induces a large birefringence.

Birefringent crystals have the ability to modulate polarized light, which has important applications in the field of optoelectronics. Waveplates are important devices in polarization optics to modulate the polarization and phase delay of light over a wide band of wavelength. However, conventional designs of half-wave plates and quarter-wave plates involve multiple birefringent crystals, and the fabrication process is complex and costly. Here, we report the discovery of a multiwavelength (532–785 nm) temperature-controlled phase modulator based on Cs4PbBr6/CsPbBr3 perovskite crystals. It is the crystal lattice expansion that is causing the variation of the birefringence factor of Cs4PbBr6/CsPbBr3 through observing crystal optical properties. The transmitted 633 nm light can be temperature-modulated to achieve the switching of optical polarization states between circularly polarized and linearly polarized states, revealing that the same crystal can switch between the functions of half-wave plates and quarter-wave plates. Other wavelengths of transmitted light can also change optical polarization states through temperature control. Given the versatility of halide perovskite-based crystals, Cs4PbBr6/CsPbBr3 crystals offer a promising approach for producing waveplates and other optical devices at a lower cost.

Birefringent crystals are important optical functional materials widely used in light polarization modulation. Generally, the larger the birefringence, the higher the modulation efficiency. Thus, it is necessary to develop crystals with a large birefringence. Herein, two planar groups, phenyl and acyl, were adopted to generate strong optical anisotropy. Then, three urea-based crystals, N-phenylurea, N,N′-diphenylurea, and acetylurea, were found, all of which exhibit a large birefringence of 0.169, 0.266, and 0.315 (at 546 nm), respectively. Although the birefringence improvement is facilitated by phenyl groups, it is restricted by their incomplete coplanar arrangement, while it achieves the maximum by acyl groups and their coplanar arrangement with urea. Moreover, these crystals all exhibit a wide ultraviolet transparency window. Therefore, this work develops three birefringent crystal candidates and also provides some new insights, which will facilitate the exploration of novel birefringent crystals.

The first mixed alkali metal borosulfate compound, Li2NaB3S2O12 (LNBSO), which contains [BO3] groups, was designed and synthesized by using a high boron-to-sulfur ratio strategy through the high temperature solution method. LNBSO exhibits a birefringence of 0.057@546.1 nm in experiments, which was mainly contributed by the [BO3] groups, and possesses a short absorption edge at 184 nm, and the space group of LNBSO is P21/c. This newly synthesized borosulfate compound holds potential as a promising birefringent material within the deep-ultraviolet wavelength range. Moreover, the investigation on the relationship among the ratio of boron to sulfur, the dimensionality of the anionic framework, and the formation of [BO3] groups has been conducted on available borosulfate, providing insights for the synthesis of borosulfate with desirable performances.

The vanadate (VO) polyhedron offers a compelling avenue for exploring birefringent materials within the infrared frequency range. Among many potential building blocks, the implementation of [VO3]∞ chains demonstrated great potential as effective birefringent functional units. In this article, we successfully synthesized the Li0.8Na0.2CsV2O6·H2O compound, which exhibits a remarkable birefringence of 0.134 at 546.1 nm, as confirmed by the experiment. Notably, the introduction of alkali metals in this compound led to a significantly shorter cutoff edge at 340 nm. Through a comprehensive investigation, Li0.8Na0.2CsV2O6·H2O has the shortest UV cutoff edge among all vanadates, whose birefringences are larger than 0.1, to the best of our best knowledge. This finding underscores the application potential of this novel material as a birefringent crystal.

Using the well-known LiB 3 O 5 as the template, by improving the angle between B 2 O 5 units in its structure to reduce birefringence, two novel birefringent crystals Li 2 MLaB 18 O 30 (M = Rb, Cs) for preparing zero-order wave-plates are obtained by a high-temperature solution method in a closed system. Interestingly, the neighboring B 2 O 5 units are aligned almost perpendicularly, making them exhibit tiny birefringence, which is much smaller (0.0032@532 nm and 0.0027@532 nm, respectively) than that of the commercial quartz crystal (Δ n ~0.0092@visible region). Moreover, the ultraviolet cutoff edges of Li 2 MLaB 18 O 30 (M = Rb, Cs) crystals are below 200 nm, demonstrating that they can be applied as zero-order waveplate materials in the deep-ultraviolet region.

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.

Two polar molybdenum(VI) iodates(V), NH4[MoO3(IO3)] (1) and KRb[(MoO3)2(IO3)2] (2), have been prepared by a hydrothermal method. They crystallize in noncentrosymmetric (NCS) space groups Pna21 and Cc, respectively. Structurally, it is interesting that compound 2 has an exclusive one-dimensional [IO3]− chain based on corner-sharing [IO4]3– units in all iodates(V). As for the properties, both compounds exhibit large second-harmonic generation responses of 4.7 × KH2PO4 (KDP) for compound 1 and 8.5 × KDP for compound 2 with phase-matching behavior. These results are in good agreement with the results of the theoretical calculations. In addition, both compounds also possess large birefringences (Δn) of 0.083 at 1064 nm and 0.146 at 1064 nm, respectively. These results indicate that the title compounds will have potential applications as nonlinear optical materials.
