摘要
A compound ammonium fluoroborate, a nonlinear optical crystal of ammonium fluoroborate, and a preparation method and use thereof; the compound has the chemical formula of NH4B4O6F with a molecular weight of 176.28, and is prepared by a solid phase reaction process; the crystal has the chemical formula of NH4B4O6F with a molecular weight of 176.28, belongs to the orthorhombic system, and has a space group of Pna21 and the following unit cell parameters: a=7.615(3) Å, b=11.207(4) Å, c=6.604(3) Å, Z=4, V=563.6 Å3. The nonlinear optical crystal can be obtained by the method of the present invention. The present invention provides uses of the nonlinear optical crystal in producing harmonic light and a deep-ultraviolet frequency-multiplied light below 200 nm; and in making a frequency multiplication generator, a frequency up or down converter or an optical parametric oscillator.
