Crystal growth, solubility, structural, optical, thermal, mechanical and electrical studies of l-arginium adipate: An organic nonlinear optical material

l-Arginium adipate (LAAD) single crystal has been grown by slow evaporation solvent technique at room temperature. The crystal structure and lattice parameters were determined for the grown crystal by single crystal X-ray diffraction studies. Single crystal X-ray diffraction analysis confirms the grown crystal has monoclinic crystal system with space group of P21. Fourier transform infra red (FTIR) spectroscopy and thermal analysis (DSC and TGA) were performed to study the molecular vibrations and thermal behaviour of the crystals, respectively. Powder X-ray diffraction analyses show the good crystalline nature. Mechanical characterization such as micro hardness studies on (1 0 0) plane were also carried out. Photoluminescence studies confirm the violet fluorescence emission peak at 400 nm. Linear optical study (UV–vis absorption) was determined by UV-Vis spectrophotometer. The dielectric constant, dielectric loss and ac conductivity of the compound were calculated at different temperatures and frequencies to analyze the electrical properties. Nonlinear optical property was discussed to confirm the SHG efficiency of the grown crystal.
