Abstract

The crystals of sulphamic acid (SA) and L-isolucine added sulphamic acid (LISA) were grown by slow evaporation method at room temperature. The XRD analysis revealed that both SA and LISA crystals exhibited orthorhombic crystal structure. The thermal stability of the grown crystals were found by thermo gravimetric and differential thermal analysis (TGA/DTA), and exhibited that the grown crystals were thermally stable up to 261o C for pure SA and 257o C for GSA crystals. The antibacterial activity of the grown was analyzed. The third order nonlinear refractive index, absorption coefficient and optical susceptibility were calculated by the Z-scan technique.
