Abstract

A potential organic nonlinear optical (NLO) single crystal based on amino acid, L alaninium oxalate (LAO) is grown using the simple chiral amino acid L alanine and oxalic acid by slow evaporation method. Grown crystals have an optimum dimension of 40 x15 x 8 mm³ with good optical quality and are characterized by powder XRD, CHN analysis, FTIR spectroscopy, TGADTA, DSC, UV/ VIS/ NIR absorption spectroscopy, photoconductivity and photoluminescence studies. The third order nonlinear optical properties of the grown crystals are investigated employing open aperture Z scan technique.

Keywords
