Single crystals of the birefringent material Ba 2 Ca(B 3 O 6 ) 2 (BCBO) with dimensions up to 40 × 28 × 10 mm 3 were successfully grown by top-seeded solution growth (TSSG) method from B 2 O 3 −NaF flux. It exhibits high transmittance in the range of 190−3000 nm with UV cutoff of 178 nm, which is much shorter than that (189 nm) of the commercial UV birefringent crystal, the high-temperature phase of BaB 2 O 4 (α-BBO). Meanwhile, BCBO crystal has large birefringence (Δn = n o − n e = 0.2524−0.0862) in the wavelength range from 178 to 3000 nm and without phase transition from room temperature to the melting point. A prototype of Glan−Taylor polarizer made from BCBO crystal showed an optical extinction ratio of 10 4 :1, which is comparable to those of commercial birefringence crystals. The experimental results demonstrate that the BCBO crystal can be a new promising birefringent crystal for UV, especially the sub-200 nm deep-UV range.

“…Birefringence is manifested by the existence of orientationdependent differences in the refractive index, which is widely used in the elds of optical polarization, optical modulation, and nonlinear optics. [1][2][3][4][5][6][7] The exploration of birefringent materials is an essential topic in the eld of optical research. [8][9][10][11][12][13][14][15] To date, a diverse range of oxide and halide birefringent materials with high chemical stability have garnered signicant interest, including MgF 2 , 16 a-BaB 2 O 4 , 17 YVO 4 , 18 TiO 2 , 19 LiNbO 3 , 20 CaCO 3 , 21 etc.…”

Birefringent crystals are important optical devices in various advanced optical systems because they can create and control polarized light. In this work, the capability of planar [B 3 S 6 ] to produce large birefringence was theoretically studied for the first time. Moreover, the first d 10 metal thioborate HgB 2 S 4 (HBS) has been synthesized successfully, which was constructed by the π-conjugated [B 3 S 6 ] and [HgS 2 ] units. Notably, HBS shows great potential to be an infrared birefringent material due to its large birefringence, Δn = 0.52 @ 1064 nm (∼4.3 × α-BaB 2 O 4 and ∼10.4 × AgGaS 2 @ 1064 nm), wide band gap of 3.36 eV, and wide transparent window (∼0.37−25 μm). To the best of our knowledge, both the birefringence and the band gap of HBS are the largest among mercury sulfides. Structure-performance analyses reveal that the π-conjugated [B 3 S 6 ] units are the main birefringence contributor and could be regarded as a good unit for designing IR birefringent materials. This work will provide direct guidance to design high performance birefringent crystals in the future.
