The first bismuth selenite fluoride, BiFSeO3, was obtained by aliovalent substitution of 2D BiOIO3. Its structure features a 3D network composed of 1D BiF chains interconnected by SeO3 groups. BiFSeO3 exhibits a very strong second harmonic generation (SHG) effect of about 13.5 times that of KH2PO4 (KDP) under 1064 nm laser radiation and 1.1 times that of KTiOPO4 (KTP) under 2.05 μm laser radiation, which is the highest among all of the metal selenites reported. It has also very simple chemical composition and can be synthesized easily under mild hydrothermal conditions.
首例碲酸铋氟化物 BiFSeO3 通过 2D BiOIO3 的等价取代获得。其结构特征是由 SeO3 基团连接的 1D BiF链构成的 3D 网络。在 1064nm 激光辐射下，BiFSeO3 的二次谐波产生 (SHG) 效应非常强，大约是 KH2PO4（KDP）的 13.5 倍，在 2.05μm 激光辐射下，大约是 KTiOPO4（KTP）的 1.1 倍，这在所有报道的金属碲酸盐中是最高的。它的化学成分也非常简单，并且可以在温和的水热条件下很容易地合成。
