氟硼酸铍(Be2(BO3)F,简写为BBF),属单斜晶系,空间群为C2.该化合物含有BO3平面三角形基团.BeO3F四面体与BO3基团连接形成六元环,通过Be-F-Be将层与层之间交叉联结起来.理论计算表明其Eg=7.80eV,吸收边在150nm;有较大的双折射率,Δn=0.0915;倍频系数计算结果显示:d22=-0.0723pm/v,d16=-0.0172pm/v,d14=-0.00928pm/v,d23=0.0053pm/v.对合成得到的材料粉末样品进行XDR物相测试验证和热分析.粉末倍频测试表明该材料的倍频讯号强度为KDP的1/4左右.实验证明BBF可能是一种潜在的紫外、深紫外非线性光学材料.
