Abstract :
Optical quality single crystals of potassium bromide were grown in the aqueous solution of Larginine by slow solvent evaporation technique at room temperature (30°C). The Face Centered Cubic structure of the grown crystal was elucidated by single crystal X-ray diffraction (SCXRD) study. The percentages of composite elements of grown material were studied through Energy Dispersive X-ray (EDX) spectrum. The Scanning Electron Microscope (SEM) reveals microstructural property of title crystal. The Fourier Transform infrared spectrum (FTIR) ensures the intermolecular interaction in the sample material. The optical transmission spectrum confirms wide range of transmission in UV-Vis-NIR region. The Z-scan technique reveals the third order nonlinear susceptibility χ(3), refractive index (n2) and absorption coefficient (β) of the sample. The thermogravimetric (TG) and differential thermogravimetric (DTA) analyses confirm the thermal stability of title compound up to 230 °C. The Vickers microhardness test reveals the appreciable mechanical strength of the crystal. The dielectric study ensures enhanced electrical properties of the grown crystal.
