The optical band gab is found to be 4.26 eV. Single crystal X-ray diffraction analysis reveals that L-PTCA crystallizes in trigonal crystal system. Graphical abstract: L-Prolinium trichloroacetate is an organic nonlinear optical crystal has been grown from the aqueous solution by slow evaporation solution growth technique.
The Kurtz-Perry powder SHG technique confirms the NLO property of the grown crystal and the efficiency of AMT crystal was found to be 1.3 times that of standard KDP crystal. Mechanical behavior was assessed using Vickers hardness testing carried out on (0 0 1) crystallographic plane. Chemical etching studies were attempted to determine the dislocation density of the grown crystal. Thermogravimetric and differential scanning calorimetric measurements were performed to study the thermal properties of the grown crystal. The optical transmittance spectrum shows that the material has a good optical transparency in the entire visible region with the UV cut-off wavelength at 234 nm. The structural perfection of the grown crystal was analyzed by high-resolution X-ray diffraction measurement. The grown crystals were characterized by single crystal XRD and the lattice parameters have been confirmed. more » - Abstract: The organic nonlinear optical material ammonium D,L-tartrate single crystal has been successfully grown by slow evaporation solution technique (SEST). Black-Right-Pointing-Pointer SHG efficiency of AMT is 1.3 times greater than that of KDP sample. Black-Right-Pointing-Pointer AMT crystal was thermally stable up to 200 Degree-Sign C. Black-Right-Pointing-Pointer The optical quality and mechanical stability of the AMT crystal was studied by UV-Vis-NIR and Vickers microhardness. Black-Right-Pointing-Pointer The crystalline perfection was investigated using HRXRD and chemical etching analysis.

The thermal behavior of the grown crystal was analyzed by thermogravimetric analysis. The nonlinear optical property was confirmed by the powder technique of Kurtz and Perry. The optical behavior of the grown crystal was examined by UV–visible spectral analysis, which shows that the optical absorption is almost negligible in the wavelength range 280–1300 nm. The FT-IR spectroscopy was used to identify the functional groups of the synthesized compound. The hydrogen bonded motifs are linked to each other to form a three dimensional network. In the crystal, molecules are linked through inter and intramolecular N-H⋯O and O-H⋯O hydrogen bonds, generate edge fused ring motif. The structural characterization of the grown crystal was carried out by single crystal X-ray diffraction at 293(2) K. = has been successfully synthesized from aqueous solution by slow solvent evaporation method.
