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 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.
