The present application discloses an inorganic compound crystal, its preparation method and use. The chemical formula of the inorganic compound crystal is Pb 2 GaF 2 (SeO 3 ) 2 Br, which belongs to the monoclinic crystal system, the space group is P2 1 , and the unit cell parameter is α=γ=90.000°, β=111.026°, Z=4. The inorganic compound crystals are prepared by a hydrothermal method. The inorganic compound crystal Pb 2 GaF 2 (SeO 3 ) 2 Br has a powder SHG coefficient of 5.2 times that of KH 2 PO 4 (KDP) under 1064 nm laser irradiation, and can achieve phase matching under 1064 nm laser irradiation, as nonlinear optics The material has good potential utilization value. |
