Appropriate amounts of l-arginine monohydrochloride and barium chloride were dissolved in double distilled water at room temperature. Transparent and defect less bulk crystal of LAMBC with dimension 6 x 5 x 3 mm3 have been grown by solution growth method. Single crystal X-ray diffraction study reveals that LAMBC crystal belongs to orthorhombic crystal system and the measured lattice parameters values are a=8.28 Å, b=9.37 Å, c=14.938 Å, α=β=γ=900 and volume V=1158.94 Å.. In Powder XRD, the powdered sample was scanned over in the range of 10 to 80º at a scan rate of 1o per minute. Thus the powder XRD pattern observed well defined Bragg’s peaks reveal that the LAMBC crystal is in good crystalline nature. FT-IR analysis was carried out to identity the various functional groups present in LAMBC. In the recorded optical transmission spectrum, the UV transparency cut-off wavelength at 307 nm and high transmission percentage of LAMBC crystal from 307 nm to 1000 nm are observed. The powder SHG efficiency of LAMBC crystal is 0.55 times that of standard inorganic KDP. Microhardness study of grown crystal of LAMBC reveals that the grown crystal possesses high mechanical strength. The dielectric properties of LAMBC crystal shows high dielectric constant in lower frequency region and decreases with increase in frequency. The surface of the grown crystal LAMBC has examined by chemical etching analysis.
