In the present work, we have grown single crystals of L-proline cadmium chloride monohydrate (LPCCM) by slow evaporation solution technique (SEST) at room temperature and recorded their live growth kinetics with the help of inverted microscope. Crystal size at various stages of growth and its corresponding morphology was also recorded. Powder X-ray diffraction (PXRD) analysis of LPCCM single crystals confirmed the orthorhombic structure. Respective values of crystallite size, strain and dislocation density have been calculated using PXRD data. Metal complex coordination of the single crystal is studied by FTIR spectroscopic. The optical properties of the grown crystals were investigated through UV-VIS spectroscopic studies and shows that the crystals have very low absorption in entire characterized wavelength range 200-800 nm. The optical band gap was calculated and found to be similar to 5.6 eV. Optical constants of the material is determined by theoretical calculations. The chemical etching study was also carried out to study the density of defects in the grown crystals. The photoluminous excitation and emission spectra and thermal property by TGA/DTA curve were recorded. Further, the mechanical properties have been studied using Vicker's microhardness tester as well as many parameters such as fracture toughness (K-c), Brittleness index (B-i) and yield strength (sigma(v)) are presented. Dielectric studies have been carried out with varying frequency and temperatures. (C) 2013 Elsevier B.V. All rights reserved.
