Growth and characterization of ULMA single crystals doped with zinc chloride

Abstract

Single crystals of zinc chloride-doped urea L-malic acid (ULMA) were grown by slow evaporation technique. Many interesting results on several properties of zinc chloride impurity added ULMA single crystals have been observed and studied. Zinc chloride doping on the growth, optical, structural and hardness properties of ULMA crystals has been investigated. The functional groups were found by FTIR analysis. Powder X-ray diffraction studies confirm the diffraction planes of the grown crystals. Single crystal XRD studies reveal the unit cell parameters. The UV-visible spectrum shows the cut-off wavelength at 225 nm. The NLO property of the grown crystals was confirmed by SHG studies.
