Growth and characterization of nonlinear optical (NLO) crystal of (((4-aminophenyl)sulphonyl) oxy)zinc(II)chloride (4-ASZC), based on zinc chloride with sulphanilic acid by the slow evaporation method has been studied and reported in this paper. The single crystal X-ray diffraction study confirmed the monoclinic system with centrometric space group P2 1 . The sharp Bragg's peak in powder X-ray diffraction analysis identifies the crystalline nature. Optical properties, such as low cut-off wavelength (251 nm), optical band gap (E g = 4.40 eV), reflectance (R), extinction coefficient (K) and refractive index (n), are calculated from the UV-vis-NIR spectrum. The presence of functional groups are confirmed by the FT-IR spectroscopy. The placement of protons and carbons was determined by the NMR technique. The photoluminescence study shows the green light emission. The grown crystal is thermally stable up to184°C. The NLO efficiency is 0.5 times greater than that of standard KDP. The mechanical properties were analysed. The dielectric constant (ε), dielectric loss (ε ), imaginary dielectric constant (ε ), AC conductivity (σ ac ) and Cole-Cole graphs were plotted. The surface morphology and the particle size of the crystal were determined by the FESEM technique. ARTICLE HISTORY

Undoped and 0.5 mol% of L-aspartic acid (LA-C 4 H 7 NO 4 ) and L-threonine (LT-C 4 H 9 NO 3 ) doped sodium acid phthalate (NaAP) single crystals were successfully grown from aqueous solution by slow evaporation solution growth technique. Single X-ray diffraction revealed that the grown crystals possess orthorhombic crystal structure and revealed lattice distortion due to impurities. The crystallinity nature of the grown crystals was analyzed by powder X-ray diffraction analysis. Functional groups and the modes of vibrations were identified by FT-IR spectral analysis. Optical transmittance shows that L-threonine doped NaAP crystal possesses higher transparency compared to undoped NaAP and L-aspartic acid doped NaAP and the band gap energy values of the grown crystals were calculated. The photoluminescence properties of the grown crystals were investigated. The mechanical strength of the grown crystals was estimated by microhardness studies. The second harmonic generation of the grown crystals was confirmed by the Kurtz and Perry technique. Antibacterial activity of the title compounds against Streptococcus pneumoniae, Escherichia coli, and Klebsiella pneumonia strains was studied.Copy Right, IJAR, 2017,.

Introduction:-Semiorganic crystals are a new category of materials recently examined for their fascinating properties and stable physiochemical properties, which are significant for device fabrication and applied research [1,2]. The high nonlinearity, high resistance to laser-induced damage, low angular sensitivity and better mechanical hardness of semiorganic crystals incorporate in the strong NLO properties and chemical flexibility of organic materials with the physical sturdiness and excellent transmittance of inorganic materials [3][4][5][6]. In addition, the approach of high NLO efficiency organic molecules with the favorable physical properties of the inorganic materials has been an active area of research in the last two decades.Organic material with high nonlinear optical coefficients combines with an inorganic material exhibiting excellent physical properties, giving semiorganic material. Hydrogen bonding of acid based interaction between organic cation and an inorganic anion of semiorganic give mechanical strong and thermally stable NLO crystals [7]. Highly

“…Hydrogen bonding of acid based interaction between organic cation and inorganic anion of semi-organic give mechanical strong and thermally stable NLO crystals [13]. Highly polarizable acid-base interactions of organic and inorganic molecules are responsible for NLO properties, as linking through a hydrogen bond network yields non-centrosymmetric structural systems as reported by Srineevasan et al (2013) [14] and Rajasekaran et al (2000) [15]. Rich demand for semi-organic complexes in optical storage devices, colour displays and optical communication systems is observable in literature.…”
