摘要: 首次以LiF-H3BO3为助熔剂,用顶部籽晶法,生长出尺寸为12 mm×13mm×5mm的Ba2B5O9Cl透明单晶.通过热性能分析证实该晶体为非同成分熔融化合物,属于正交晶系,空间群Pnn2,晶胞参数为a=1.1576(2) nm,b=1.1619(2)nm,c =0.66874(13) nm,V=0.8994(3) nm3,Z=4.该晶体中含有BO3和BO3基团,具有三维网状的晶体结构.Ba2B5O9Cl粉末的非线性光学效应约为KDP的3.5倍,同时还进行了红外、漫反射光谱性能的研究.
英文摘要: Single crystals of Ba2B5O9Cl with sizes up to 12 mm × 13 mm × 5 mm have been grown by top seeded solution growth method using LiF-H3BO3 as the flux for the first time. The TGA-DSC experiments proved that Ba2B5O9Cl melts incongruently. It crystallizes in the orthorhombic system, space group Pnn2, with unit-cell parameters a=1.1576(2) nm, b=1.1619(2) nm, c=0.66874(13) nm, V=0.8994(3) nm3, Z=4.There are BO3 and BO4 groups in the Ba2B5O9Cl crystal and it exhibits a three-dimensional network structure. Nonlinear optical efficiency of Ba2B5O9Cl is about 3.5 times that of KDP. The infrared spectrum and the UV-Vis diffuse reflectance spectroscopy were also performed on the reported material.
