第一个亚硒酸铋氟化物，BiFSeO3，通过异价取代2D BiOIO3获得。其结构特征是由SeO3基团互连的一维[BiF]（2+）链组成的三维网络。BiFSeO_3在1064 nm激光辐射下具有很强的二次谐波产生（SHG）效应，约为KH_2PO_4（KDP）的13.5倍，在2.05 μ m激光辐射下约为KTiOPO_4（KTP）的1.1倍，是所有已报道的金属硒化物中最高的。它也具有非常简单的化学组成，并且可以在温和的水热条件下容易地合成。
The first bismuth selenite fluoride, BiFSeO3, was obtained by aliovalent substitution of 2D BiOIO3. Its structure features a 3D network composed of 1D [BiF](2+) 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 mu m 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.
