Abstract

利用高温固相反应法合成出Pb2[B5O9]Br硼酸盐粉末。采用PbO-NaF做复合助熔剂,利用顶部籽晶法获得了3 mm×3 mm×1.5 mm的透明单晶,X射线粉末衍射数据显示,该晶体属正交晶系,Pnn2空间群,晶胞参数为a=1.1524(1)nm,b=1.1431(1)nm,c=0.65399(3)nm。红外光谱测量证实晶体结构中含有BO33-和BO45-基团。反射光谱表明Pb2[B5O9]Br的紫外吸收边在250 nm左右。Pb2[B5O9]Br粉末倍频效应(SHG)测试表明该化合物具有非线性光学效应,信号强度约等同于β-BaB2O4。

Other Abstract

Pb2[B5O9]Br borate powder was synthesized by the high-temperature solid-state method. The transparent single crystal of Pb2[B5O9]Br was grown by top-seeded solution growth method using the powder as raw material. The typical crystal size was about 3 mm×3 mm×1.5 mm. X-ray diffraction analysis show that it is same as the one reported in the literature. It belongs to the orthorhombic system, space group Pnn2, and lattice parameters a=1.1524(1) nm, b=1.1431(1) nm, c=0.65399(3) nm. The measurement of the infrared spectrum indicate that the basic anionic group is the BO33- and BO45-. The reflection spectrum show that the cut-off wavelength of Pb2[B5O9]Br is about 250 nm. Pb2[B5O9]Br exhibits a powder second harmonic generation (SHG) effect similar to that of β-BaB2O4.
