摘要

利用自制的晶体生长装置，制备了非线性光学材料D-(-)-丙氨酸(DALA)单晶。用慢蒸发溶液法(sse)生长了DALA晶体。采用单晶x射线衍射、高分辨x射线衍射(HRXRD)、紫外-可见-近红外光谱和CD光谱对生长晶体进行了表征。文中还报道了维氏显微硬度、激光损伤阈值和二次谐波产生效率的测量结果。还进行了热学和电介质研究。

Bulk Growth and Characterization of D-(–)-Alanine Single Crystals

Single crystal of D-(–)-alanine (DALA), a non-linear optical material from the amino acid family was grown using a home-made crystal growth setup. The crystals of DALA were also grown by slow evaporation solution technique (SEST). The grown crystals were characterized by using single crystal X-ray diffraction, high resolution X-ray diffraction (HRXRD) and UV-vis-NIR and CD spectroscopy. Measurements of Vicker’s microhardness, laser damage threshold (LDT) value and second harmonic generation (SHG) efficiency are also reported. Thermal and dielectric studies were also carried out.
