“…The observed lattice parameter values of pure and LHMHC dihydrate doped NaAP crystals are found to be a=6.75 Å, b=9.33 Å, c=26.65 Å, α=β=γ=90° and the volume of the unit cell was found to be 1678 Å 3 for pure NaAP crystal and a=6.77 Å, b=9.38 Å, c=26.75 Å, for LHMHC dihydrate doped NaAP crystal, the volume of the unit cell was found to be 1699 Å 3 and the grown crystals belong to the space group B2ab which is in good agreement with the reported values [4,6] of pure NaAP crystal. The slight variations in the cell parameters indicated the incorporation of LHMHC dihydrate into the crystal lattice of pure NaAP crystal.…”

“…In the case of dopants, the same peaks were observed with some slight shifts in the undoped spectrum. All these bond assignments are in excellent agreement with that of the reported values [4]. Here the shifting of peaks denotes that LHMHC dihydrate doped NaAP is added into the crystal lattice of pure NaAP successfully.…”

“…In this series, sodium hydrogen phthalate [Na(C 6 H 4 COOH-COO)] also called sodium acid phthalate (NaAP) is a semiorganic material that goes to orthorhombic class of alkali acid series, which is having laser-induced damage threshold and the values of SHG efficiency much higher than that of KAP crystal with non-hygroscopic nature [4]. NaAP consists of Na ions, phthalate ions and water molecules.…”

The pure and semiorganic material of L-Histidine monohydrochloride dihydrate (LHMHC dihydrate) doped sodium acid phthalate (NaAP) single crystals were effectively grown from deionized water by slow evaporation solution technique. Single crystal X-ray diffraction is employed to know the precise information about the crystallographic structure and also the title materials are orthorhombic crystal system with space group B2ab. The interaction of various functional groups was recognized by FT-IR spectral study. The title materials are optically transparent and having a lower cut-off wavelength as 300 nm, thereby confirming the enhancement of nonlinear optical property and optical band gap of the pure and LHMHC dihydrate doped NaAP crystals have been determined as 3.5 eV and 4 eV by UV-Visible studies. The dielectric constant and dielectric loss of the pure and LHMHC dihydrate doped NaAP crystals decrease as the frequency of applied field increases at the end. The mechanical behaviors of the grown crystals were assessed by Vickers microhardness activities. The SHG efficiency of the grown crystals confirms NLO behavior of green colour emission to offer frequency doubling process for photoelectronic applications.

“…This is due to the incorporation of L-threonine and L-aspartic acid in the NaAP crystal lattice. The calculated lattice parameter and unit cell volume are given in Table 1 and which is in good agreement with the early literature [10]. Powder X-ray diffraction pattern of all the grown crystals was recorded on X'pert PRO powder X-ray diffraction (40 kV) using Cu-Kα radiation of wavelength λ = 1.5406 Å. Powder XRD patterns of undoped NaAP, LA-NaAP and LT-NaAP crystals are shown in Fig.…”

“…The C=O stretching vibration are ascribed at 1603 cm -1 , 1606 cm -1 and 1609 cm -1 for undoped NaAP, LA-NaAP and LT-NaAP respectively. The group of C-H out-of-plane bending vibrations observed at (861 for undoped NaAP, LA-NaAP and LT-NaAP respectively [10,11]. Very slight variations in the position of vibrational bands of NaAP were observed due to amino acids dopants.…”

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

Raman-induced many-phonons Stokes and antiStokes generation in a orthorhombic crystals KHC6H4(COO)2 and (NH 4 )HC 6 H 4 (COO) 2 under picosecond pumping has been observed. All recorded nonlinear lasing lines in the visible and near-IR regions are identified and attributed to the χ (3) -promoting vibration modes of these orthorhombic phthalates.
