“…This dipolar nature exhibits peculiar physical and chemical properties in amino acids, thus make them ideal candidate for NLO applications. 6 Thiourea molecule is an interesting inorganic matrix modifier due to its large dipole moment and its ability to form an extensive network of hydrogen bonds 7 . The nonlinear optical properties of some of the complexes of thiourea, such as bis-thiourea cadmium chloride (BTCC), bis-thiourea zinc chloride (BTZC), and potassium thiourea bromide (PTB) have gained significant attention in the last few years because both organic and inorganic components in it contribute to the process of second harmonic generation.…”

Background: We report on synthesis, growth and characterization of Bis-thiourea L-lysine monohydrochloride (BTLM) crystal.Methods: Bis-thiourea L-lysine momohydrochloride (BTLM) crystal were grown by solution growth method in the molar ratio 1:1 at room temperature.Results: Transparent and defect free crystal of BTLM were harvested in the period of 40-45 days with dimension 7mm × 4mm × 2mm. Single crystal XRD analysis revealed that the crystal system belongs to Orthorhombic with cell parameters a= 14.41 Å, b= 5.89 Å and c= 15.52 Å. The sharp and well defined Bragg peaks observed in the powder XRD pattern confirm the crystalline nature of BTLM crystal. The presences of functional groups in the grown crystal BTLM were identified by FT-IR analysis. The fluorescence spectral study was carried out in the range of 280–500 nm. Second harmonic generation (SHG) of powdered BTLM sample was tested using Nd: YAG laser and is found to be 0.55 times that of potassium dihydrogen orthophosphate. The mechanical strength of the BTLM crystal was evaluated and it describes that the Vickers hardness number of BTLM is found to be increase with the applied load. The work hardening co-efficient (n) has been calculated from the slope of straight line between log P and log d. The dielectric study of BTLM was carried out as a function of frequency at different temperature.Conclusions: From the result we confirm that the BTLM crystals have good physicochemical properties. So, the grown BTLM crystal was suitable candidate for nonlinear optical applications.

“…Metal organic coordination compounds as non linear optical materials have attracted much more attention for their high NLO coefficients, stable physico-chemical properties and better mechanical intension. Many metal organic coordination complexes of thiourea materials with good NLO effects have been designed and synthesized [9][10][11][12][13][14] . Pfeffer et al 15 reported the anion recognition using pre-orgranized thiourea functionalized polynorbornance receptors.…”

The IR and Raman spectra of the title compound have been recorded and analyzed. The harmonic vibrational wavenumbers were calculated theoretically using Gaussian09 software package. Wavenumbers were calculated at HF and DFT levels. The observed wavenumbers were found to be in agreement with the calculated (DFT) values. The small differences between experimental and calculated vibrational modes are observed. It must be due to the fact that experimental results belong to solid phase and theoretical calculations belong to gaseous phase. The first hyperpolarizability, infrared intensities and Raman activities are reported.

“…In recent years, growth and studies of the organic NLO materials have been emphasized due to their important physical and chemical properties essential for electro -optic modulation, optical switching, high laser damage threshold, second harmonic generation and nonlinear optical applications [1][2][3][4][5]. Even though organic materials possess high non-centro symmetric behaviour, wide bandwidth potential and high nonlinear activity but they have lesser thermal and mechanical stability.…”
