Synthesis and thermal, optical, dielectric and mechanical properties of l-asparagine sodium nitrate single crystal

Abstract

Single crystal of l-asparagine sodium nitrate (LASN) was grown from aqueous solution by room temperature solution growth technique. The grown crystal was characterized by single crystal X-ray diffractometry (XRD), FTIR and optical absorption spectrum. The micro hardness test of the sample revealed that the crystal belongs to the soft category of materials. The dielectric response of the crystal with varying frequencies was studied and reported. The thermal stability of the compounds has been determined by TG-DTA curves. The SHG relative efficiency of LASN crystal was found to be inferior than that of KDP.
