Functional Profiling of L-Alanine Diglycine Picrate (LADGP) Single Crystal for Nonlinear Optical Enhancement

Abstract

The L-Alanine Diglycine Picrate (LADGP) single crystal was cultivated employing the slow evaporation solution method under usual atmospheric conditions. The structural confirmation for the LADGP crystalline material was conducted via single crystal X-ray diffraction (SXRD), revealing a monoclinic structure having the P2₁/n space symmetry. The powder X-ray diffraction (PXRD) was utilized for ascertaining the crystalline structure of the LADGP crystal. Vibrational assignments and identification of functional moieties of the LADGP single crystal were achieved through Fourier Transform Infrared spectroscopy. Microhardness measurements were performed to probe the mechanical robustness of the LADGP crystal, highlighting its exceptional durability. The optical qualities in the LADGP crystal were evaluated with UV-visible near-infrared spectroscopy. Electrical properties of LADGP crystal were investigated through conducting dielectric experiments (constant and loss) as a varying with frequency at three different temperature.The photoconductivity measurements showed that the LADGP crystal becomes more conductive when exposed to different types of light. The LADGP crystal exhibited a laser damage threshold (LDT) of 2.6 GW/cm², suggesting its aptness for laser-related uses. The nonlinear third-order susceptibility was assessed and analyzed using Z-scan techniques.
