A semiorganic nonlinear optical material, lithium bis-L-malato borate (LBMB) (molecular formula C8H8BLiO10), has been synthesized, and single crystals grown from an aqueous solution, by the method of slow evaporation at 30 degrees C. Crystals of size up to 7 mm x 3 mm x 2 mm were harvested and characterized by powder and single crystal X-ray diffraction and Fourier transform infrared techniques to confirm the identity of the compound formed. The TG-DTA results establish the good thermal stability of the material. The UV-Vis-NIR spectral study reveals that the material has a wide transparency window (230-1500 nm) with a lower cutoff at 230 nm. Kurtz powder test with a Nd:YAG laser indicates the production of SHG output.
一种半有机非线性光学材料，双-L-苹果酸硼酸锂（LBMB）（分子式为C8H8BLiO10）已通过在30℃下缓慢蒸发的方法从水溶液中合成并生长出单晶。收获了尺寸达7mm×3mm×2mm的晶体，并通过粉末和单晶X射线衍射以及傅里叶变换红外技术对其进行表征，以确认所形成化合物的身份。热重-差示热分析结果表明该材料具有良好的热稳定性。紫外-可见-近红外光谱研究表明，该材料具有宽透明窗口（230-1500nm），在230nm处有较低截止波长。用Nd:YAG激光进行的库尔茨粉末测试表明产生了倍频输出。
