Abstract :

L–alanine is a conditionally essential amino acid and it is an important source of energy for muscle tissue, the ain and central nervous system. L–alanine is a nonlinear optical (NLO) material and a source of second harmonic generation. In this work, the properties of L–alanine crystal have been improved by adding sodium nitrate as the dopant. The single crystals of pure and sodium nitrate doped L–alanine were grown by slow evaporation method and the grown crystals were characterized by studies like XRD studies, SHG studies, mechanical studies, optical studies and dielectric studies and the obtained results are discussed.
