SYNTHESIS, GROWTH AND CHARACTERIZATION OF SEMIORGANIC NONLINEAR OPTICAL CRYSTAL: L-ARGININE MONOHYDROCHLORIDE BARIUM NITRATE (LAMBN)

Materials Science- Crystal Growth

Appropriate amounts of l-arginine monohydrochloride and barium nitrate were dissolved in double distilled water at room temperature. Transparent and defect less bulk crystal of LAMBN with dimension 6 x 5 x 3 mm3 have been grown by solution growth method. Single crystal X-ray diffraction study reveals that LAMBN 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=90º 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 LAMBN crystal is in good crystalline nature. FT-IR analysis was carried out to identity the various functional groups present in LAMBN. In the recorded optical transmission spectrum, the UV cut-off wavelength at 262 nm and high transmission percentage of LAMBN crystal from 262 nm to 1000 nm are observed.
