An Investigation on Structural, Optical, Thermal, and Dielectric Analysis of L-Lysine Iodide Semiorganic Nonlinear Optical Single Crystal for Opto-electronic Application

A single crystal of L-lysine iodide (LLI) was created by utilizing a room-temperature slow evaporation approach. The monoclinic of the crystal lattice system was confirmed by estimating the lattice parameters of the synthesized single crystals using single crystal X-ray diffraction analysis. The crystalline structure and planar indexing were confirmed by powder XRD. In order to confirm that the produced LLI crystals included functional groups, the FT-IR spectra were analyzed. Spectra of visible, near-infrared, and ultraviolet light (ranging from 200 to 1100 nm) were analyzed and the cutoff wavelength of 268 nm. Vickers microhardness tester was used to find out how strong the formed crystal was mechanically stable. From 50 Hz to 3 MHz, the dielectric response of the manufactured crystal was studied at different temperatures. Thermogravimetric analysis used to look at the thermal characteristics. Human pathogens were the primary focus of antimicrobial research. Using scanning electron microscopy (SEM), the surface characteristics of the generated crystal were examined. The produced LLI crystal was recommended for use in opto-electronic and biological applications.
