Dr. J. Thomas Joseph Prakash, M. Lawrence . Article:Growth and characterization of pure and L-lysine doped Zinc (tris) thiourea sulphate crystals. International Journal of Computer Applications. 8, 3 ( October 2010), 36-39. DOI=10.5120/1190-1662
Single crystals of Zinc (tris) thiourea sulphate (ZTS) doped with basic amino acid l-lysine were grown successfully by slow evaporation method at ambient temperature. The concentration of dopants in the mother solution was varied from 0.1 mol% to 0.5 mol%. The solubility data for all dopants concentration were determined. There is a drastic change in morphology due to doping which is also reflected in the X-ray diffraction pattern. The Fourier transform infrared spectroscopy study confirms the incorporation of l-lysine into ZTS crystal. The doped crystals are optically better and more transparent than the pure ones having wide transmission spectra lying between 240 and 1200 nm. The nonlinear optical (NLO) property of the grown crystal has been confirmed by Kurtz-power second harmonic generation (SHG) test. The dopants increase the hardness value of the material and it also depends on the concentration of the dopants. Results are discussed.
