“…The strong luminescence broad peak at 432 nm was observed and is due to intermolecular interactions of lattice vibrations and indicates that the grown crystal has a violet fluorescence emission. This property of having strong emission in this range may lead to potential application of this material in optoelectronic devices [18]. The materials with photoluminescence of violet and deep red are found to be more useful for OLED applications and optical data storage applications [19].…”

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.

“…34 Although this crystal has a lower cut-off at 450 nm, it is still better compared to those of potassium p-nitrophenolate, guanidinium pnitrophenolate crystal having lower cut-offs at 510 nm and 505 nm, respectively. [8][9] The very low absorption in the entire region of 480-110 nm enables it to be a good candidate for opto-electronic and NLO applications. Below 280 nm the absorbance raises which may be due to the electronic transition π-π* taking place in benzene ring of SPNPD material.…”

Novel non-linear sodium para-nitrophenolate dihydrate (SPNPD) single crystals were grown by controlled evaporation method. Various functional groups and chemical bonding were identified by FTIR and Raman analysis. Hirshfeld surface and fingerprint plot were drawn and analyzed for the intermolecular interactions present in crystal structure. UV-visible studies indicate the high transmittance of crystals in visible region with a wide band gap 6.12 eV. In photoluminescence spectrum, a sharp broad emission peak centered at 525 nm indicates green emission. In dielectric study a broad peak with low dielectric constant value was observed at 34 °C which may be due to ferroelectric to paraelectric transition. Piezoelectricity was confirmed by determining the piezoelectric charge coefficient (d 33 =2.24 pC/N). The hysteresis loop with values of remnant polarization and coercive field as 2.67 µC/cm 2 and 7.43 kV/cm, respectively. Piezo-/ferroelectricity were reported for the first time in p-nitrophenolate based compounds. SHG efficiency of this material was found to be 4.15 times of that of KDP. Mechanical strength was confirmed from Vicker's microhardness study and voids volume. Thus promising piezoelectric, ferroelectric behavior of material along with high SHG efficiency and low dielectric constant, established SPNPD as a potential material for transducer, optoelectronics and nonvolatile memory devices applications.

“…The common wisdom has been that an optical material should have a large charge transfer and the optical transparency with less dislocation density. In recent years, search for organic single crystal in the application of telecommunication, frequency doubling and optoelectronics has been increased considerably [4][5][6][7][8]. This is because of their efficient physicochemical properties such as molecular nonlinearity over a broad frequency range, low cost, low dielectric constant, inherent synthetic flexibility, high optical damage threshold (>10 GW/cm 2 ), ultrafast response with better processability, ease of fabrication and possible integration into devices.…”
