A new nonlinear optical crystal L-histidine potassium pentaborate single crystal was grown from aqueous solution by the slow evaporation solution growth technique to analyse its suitability for NLO device applications. It belongs to the orthorhombic crystal system which is confirmed by single crystal X-ray diffraction analysis. The UV-visible analysis was carried out on LHKB 5 crystal to find out cut-off wavelength and the energy gap of the material was found to be 245 nm and 5.05 eV. The presence of L-histidine potassium pentaborate on grown material was confirmed by FTIR analysis. TG-DSC analysis determines that the material has two stages of decomposition and it has three stages of weight loss. From DTA curve a sharp endothermic peak at 192.45°C shows good crystallinity and corresponds to the melting of the grown crystal. The mechanical strength of the material is calculated using Vicker's microhardness. Grown crystal shows that the material is very much suitable for a second harmonic generation and frequency conversion applications.

“…The UV-Vis spectrum provides structural information because the absorption of UV and visible light involves the promotion of the electrons in σ and π orbitals from the ground state to higher energy states [10,11]. The optical transmission is very important to identify the potential of the NLO material, because the material can be of utility only if it has wide transparency window and reduced absorption around the fundamental and second-harmonic wavelength [12,13].…”

2-Ammoniumbenzamide trioxonitrate crystals (2-ABN) were prepared and grown at room temperature. This compound crystallizes in the orthorhombic system with non-centrosymmetric P2 1 2 1 2 1 space group. The unit cell dimensions are a = 4.8900(9) Å, b = 9.5541(19) Å, c = 18.961(4) Å with V = 885.8(3) Å 3 and Z = 4. The structure refined to a reliability R factor of 4.34%. The 2-ABN structure consists of 2-ammoniumbenzamide cations (C 7 H 9 N 2 O +) and trioxonitrate anions (NO − 3) interconnected by hydrogen bonds originating from amine group donors [N−H • • • O], so as to build a three-dimensional arrangement. The crystal structure, the thermal behaviour and the IR spectroscopic studies were discussed. The optical studies reveal that the 2-ABN crystal could be a good candidate for nonlinear optical devices. The dielectric properties, real and imaginary dielectric permittivities (ε and ε) and dielectric loss tangent (tan (δ)), of the crystal at different frequencies of the applied field are reported.

“…One of the advantages in working with organic materials is that they allow to have the desired chemical structure and hence the properties for the required nonlinear optical applications [4]. Amino-acid family single crystals have been well-established as really possible second-order NLO materials [5, 6, 7]. Amino acids are fascinating materials for NLO applications as they possess deprotonated carboxylic acid group (COO − ) and protonated amino group (NH 3 + ).…”

Glycyl-L-Valine (GLV) crystals were grown using distilled water as the solvent at room temperature by solution growth technique. Powder X-ray diffraction confirms the crystalline quality of GLV crystal. The molecular structure of GLV crystal was identified by 13 C NMR spectral studies. The nonlinear optical (NLO) behavior of the crystal was found to be ∼4.3 times greater than that of potassium dihydrogen orthophosphate. FT-Raman and FT-IR spectra of the GLV were recorded and complete functional group assignment of the determined vibrational bands of GLV have been reported. Density functional theoretical method (DFT) was performed using B3LYP with the 6-311+G (d, p) basis set and the results were compared with the experimental values which confirm the intermolecular interactions responsible for the enhanced NLO activity of the molecule, as evident from NBO and Hirshfeld analyses. The calculated HOMO and LUMO energies show that charge transfer occurs within the molecule. In addition, the molecular electrostatic potential (MEP) analysis, Mulliken atomic charges of the GLV molecule has been investigated using theoretical calculations.
