title: Effect of zinc chloride on the growth and characterization of L-proline cadmium chloride monohydrate semiorganic NLO single crystals.
abstract: Single crystals of zinc doped L-proline cadmium chloride monohydrate were successfully grown from aqueous solution by slow evaporation method at room temperature for different molar concentration of zinc chloride. The structural properties of grown crystals have been studied by single crystal X-ray diffraction, powder X-ray diffraction studies and Fourier transform infrared spectral analysis. The incorporation of the dopant (zinc chloride) into L-proline cadmium chloride monohydrate crystal lattice has been confirmed by EDAX analysis. UV-Vis spectral analyses showed that the doped crystals have lower UV cut-off wavelength at 200 nm combined with very good transparency about 85% in a very wide range. The second harmonic generation efficiency test has been carried out and results are discussed. The 0.2 and 0.4 mol Zinc chloride doped crystals were thermally stable up to 208.9 °C and 211.9 °C respectively. The electrical properties have been studied by dielectric constant studies. All results are compared with the results of pure L-PCCM crystals.
