Abstract

The title compound, β – alanine cadmium chloride (BACC), a new semiorganic nonlinear optical (NLO) crystal is grown by slow evaporation technique. The Powder X – Ray Diffractogram of the crystal has been recorded and the various planes of reflection are identified. The qualitative analysis on the crystal has been carried out using Fourier Transform Infrared (FTIR) and Fourier Transform Raman spectral measurements. Also, the presence of hydrogen and carbon in the grown crystal was confirmed by proton and carbon NMR spectral analyses. The percentage of cadmium in the crystal was determined by Atomic Absorption Spectroscopy (AAS). Optical behaviour such as UV – visible – NIR absorption spectrum and Second Harmonic Generation (SHG) for the crystal were investigated. The mechanical strength of the grown crystals was found by using Vickers microhardness tester. The thermal stability of the crystal was analyzed with the aid of Thermo Gravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC).
