“…www.crt-journal.org spectra of both LHB and LHC was studied by Petrosyan et al [7] and confirmed that they are isostructural. Interestingly these works on LHC were restricted to the solving of crystal structure and SHG preliminary studies only, other properties are not yet reported.…”

“…Besides these, the morphology, hardness along with differential thermal analysis (DTA), thermogravimetric analysis (TGA), Differential Scanning Calorimetry (DSC) and photoconductivity studies have also been done and reported by us [5,6]. LHC is one such promising semiorganic nonlinear optical material that belongs to the histidine-complex family which is isostructural to LHB [7]. A thorough scan of literature reveals that neutron and x-ray diffraction studies have already been reported [8,9], the compound was further refined on the basis of the intensity data collected by the diffractometer method [10].…”

Good optical quality single crystal of L-histidine hydrochloride monohydrate (LHC) a novel semi organic NLO material was grown by slow solvent evaporation technique. The crystal was characterized by X-ray diffractometry (XRD), Fourier Transform Infra-red (FTIR), UV-Vis-NIR, TGA, DTA, microhardness and solubility studies. The SHG efficiency is found to be higher than that of KDP crystal. The dielectric constant and dielectric loss of the crystal was studied as function of frequency and the results are discussed. Photoconductivity studies were also carried out which reveals the positive photoconducting properties of the sample.

INTRODUCTIONNowadays, much consideration was provided to the nonlinear optical materials, which are the main focus of many research works going on around the world. The role of organic non-linear optical (NLO) materials with large optical nonlinearity in the fabrication of devices in telecommunication, optical information processing and high optical disk data storage is immensely significant [1][2][3][4][5][6][7]. Organic materials are the prime choice of researchers because they have tendency to show higher order of non-linearity. The laser beam interacts with the delocalized π-electrons existing in the organic molecule produce non-linear polarization. The non-linear susceptibility of an organic material would be larger when it has donor-acceptor conjugated molecular systems. Normally amino acids have the tendency to crystallize in a non-centrosymmetric form which is useful for non-linear optical applications. A sequence of second order/third order NLO active materials composed of L-Lysine have been synthesized, such as, L-lysinium picrate, L-Lysine adipate, L-lysine acetate, tetra L-Lysine alanine mono hydrochloride dehydrate [8][9][10][11]. From the coordination chemistry, 5-sulfosalicylicacid (5SSA) is especially an attractive ligand, possessing three potential coordination groups such as OH, . L-Lysinium 5-sulfosalicylate (LL5SS) has been synthesized and grown by solution growth method at room temperature using deionized water as a solvent. The crystal structure of the materials was solved by single crystal X-ray diffraction analysis and it was found that the material has monoclinic system with the space group P21. Fourier transform infrared spectral study was carried out to confirm functional groups present in the crystal. The optical absorption study shows that the crystal is transparent in the entire visible region with a cut-off wavelength of 324 nm. Photoluminescence studies were also carried out to identify the excitation emission of the grown LL5SS crystal. Dielectric study was performed on the single crystal to study the power dissipation of the material in the presence of alternating electric field. Thermal stability has been assessed by thermo gravimetric analysis. Mechanical parameters were calculated. The laser damage threshold value of LL5SS crystal was estimated to be 5.6 GW/cm 2 using a Nd:YAG laser. The Kurtz and Perry powder SHG efficiencies were measured. Non-linear refractive index (n2), non-linear absorption coefficient (β) and third-order non-linear optical susceptibility (χ 3 ) values of LL5SS were found from Z scan technique.

“…Discovery of semi-organic nonlinear properties in L-arginine phosphate (LAP) has played a major role in both attracting the attention to crystalline salts of amino acids and working out the concept of semi-organic crystals [1]. Petrosyan et al [2] derived some semi-organic nonlinear optical crystals of L-histidine salts and reported the interaction with various acids. Recently our group has reported the effect of solvent normality on the growth of L-tyrosine bromide single crystals [3].…”

Single crystals of semi-organic L-histidine hydrobromide have been grown by slow evaporation technique from a mixture of L-histidine and hydrobromic acid in aqueous solution at ambient temperature. From high-resolution X-ray diffraction analysis, the crystalline perfection of the grown crystal has been studied. Single crystal X-ray diffraction analyses, Nuclear Magnetic Resonance spectral analysis, Thermo-Gravimetry (TG), Differential Thermal Analysis (DTA) and hardness test have been employed to characterize the as-grown crystals. The UV cutoff wavelength of the grown crystal is below 300 nm and has a wide transparency window, which is suitable for second harmonic generation of laser in the blue region. Nonlinear optical characteristics have been studied using Q switched Nd:YAG laser (), = 1064 nm). The second harmonic generation conversion efficiency of the grown crystals confirms their suitability for frequency conversion applications.
