Abstract

L-arginine semi-oxalate (LASO) single crystals were grown by slow evaporation method. The crystal crystallizes in triclinic structure with P1 symmetry and the unit cell parameters of grown crystals were evaluated by single crystal X-ray diffractometer to confirm the triclinic structure of the crystal. The investigation on the mechanical property was carried out using Vickers micro hardness tester. Etch pattern of hillocks were observed on the surface of grown crystal due to reactions of the etchant with dislocations sites. Second harmonic generation studies were performed by Kurtz and Perry method to confirm the nonlinearity of the grown crystal. These preliminary investigations suggest that the present compound L-arginine semi-oxalate (LASO) single crystals can serve as a potential candidate for optoelectronic applications..
