Growth, Structural, Spectral and Optical Studies on Pure and L-Alanine Mixed Bisthiourea Cadmium Bromide (LABTCB) Crystals
ABSTRACT
Pure bisthiourea cadmium bromide (BTCB) and 1 mole % L-alanine mixed bisthiourea cadmium bromide (LABTCB) single crystals have been grown by slow evaporation method. The grown crystals have been characterized by single crystal XRD analysis, powder XRD analysis, FTIR analysis, UV-Vis-NIR analysis and SHG studies. XRD analysis confirms the crystalline nature of the materials. The addition of L-alanine changes the crystal structure from orthorhombic to tetragonal. The presence of various functional groups present in the pure BTCB and LABTCB crystals have been confirmed by FTIR analysis. The UV-Vis-NIR spectrum shows the transmission characteristics of the crystals. The SHG study depicts the nonlinear optical efficiency of the crystals.
