Growth and characterization of amino acid (glycine and valine) substituted l-arginine diphosphate single crystals

The family of l-arginine phosphate single crystals is one of the most promising semiorganic non-linear optical materials. Single crystals of amino acid (glycine and valine) substituted l-arginine diphosphate (GLADP and VLADP) are grown by slow evaporation technique. The growth conditions and surface morphology of the crystals are studied and the grown crystals are confirmed by XRD. The SHG in the sample is confirmed by the Kurtz powder technique. The crystals are characterized by FTIR, optical absorption, thermal, microhardness and photoconductivity studies.
