Abstract

A new semiorganic crystal, L-asparagine potassium chloride (LAPC) has grown by slow evaporation technique. The crystals were subjected to various characterized techniques. Powder x-ray diffraction (PXRD) analysis confirms the crystalline nature. The presence of various functional groups was identified by FTIR spectroscopic technique. UV–Vis spectrum indicates that the crystal has good transmittance in the entire visible region. The grown crystal was thermally stable up to 103 ºC as determined by TG/DTA studies and mechanical stability was measured by Vicker’s microhardness test. The powder Second Harmonic generation test was studied by modified Kurtz–Perry method using Nd:YAG laser with fundamental wavelength of 1064 nm..
