Abstract

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.
