非线性光学（NLO）材料是未来光电技术的重要组成部分，因为它们可以拓宽普通激光源提供的可调谐波长范围。然而，一个实用的NLO材料的必要先决条件是相当严格的。因此，相当大的努力已集中在寻找可能的NLO材料上。本文报道了两种不对称的无铍硼酸盐Pna21-和P $$\bar 6$$

m- ba3mg3 (BO3)3F3具有nlo -有利的2∞[Mg3O2F3(BO3)2]层状结构。通过多次实验验证了两种多晶之间的可逆相变。光学测量表明Pna21-Ba3Mg3(BO3)3F3具有紫外NLO应用所需的光学性质。值得注意的是，Pna21-Ba3Mg3(BO3)3F3具有较大的激光损伤阈值、深紫外截止边、良好的各向异性热膨胀以及在水中的不溶性。这些光学性能可以媲美或优于商用NLO材料β-BaB2O4，这使得Pna21-Ba3Mg3(BO3)3F3成为一种很有前途的紫外NLO材料。
Nonlinear optical (NLO) materials are the vital components of future photoelectric technologies as they can broaden the tunable wavelength range supplied by common laser sources. However, the necessary prerequisites for a practical NLO material are rather strict. Accordingly, considerable efforts have been focused on finding potential NLO materials. Here we report two asymmetric beryllium-free borates Pna21- and P$$\bar 6$$

2m-Ba3Mg3(BO3)3F3 featuring NLO-favorable 2∞[Mg3O2F3(BO3)2] layered structures. The reversible phase transition among two polymorphs was demonstrated by multiple experimental tests. The optical measurements reveal that Pna21-Ba3Mg3(BO3)3F3 possesses the optical properties required for ultraviolet NLO applications. Remarkably, Pna21-Ba3Mg3(BO3)3F3 has a large laser damage threshold, a deep-ultraviolet cutoff edge, a favorable anisotropic thermal expansion as well as the capacity of insolubility in water. These optical properties can be comparable or superior to that of commercial NLO material β-BaB2O4, which make Pna21-Ba3Mg3(BO3)3F3 a promising ultraviolet NLO material.
