Investigation on the growth, spectral, thermal, laser and optical properties of glycinium 2-carboxy 6-nitrophthalate single crystal

Abstract Glycinium 2-carboxy 6-nitrophthalate (G3N) has been grown by slow evaporation method at ambient temperature using water solvent in 1:1 M ratio. Single crystal XRD study confirmed that the G3N crystal having a monoclinic structure with space group P21/c. The solid-state parameters like Fermi energy, Penn energy, Plasma energy, and polarizability were estimated theoretically. The crystalline quality of grown crystal was scrutinized by High-resolution XRD study. The mode of vibrations and presence of functional groups in the G3N compound was identified from the vibrational analysis. The lower cut-off wavelength of the G3N crystal is endowed to be 377 nm and the calculated band gap energy is 3.09 eV. Photoluminescence (PL) property of G3N crystal was studied. The imaginary (Im (χ) (3) = 0.43 × 10−6 esu) and real parts (Re (χ) (3) = 5.68 × 10−6 esu) of the third order susceptibility values were determined from Z-scan studies. The surface laser damage threshold value of G3N crystal was endowed to be 6.22 GW/cm2 using an Nd: YAG laser. TG-DSC analysis divulges that the crystal was thermally steady up to 184 °C. The dielectric manner of a G3N crystal was evaluated in the frequency between 40 and 70 Hz at various temperatures. The hardness of G3N crystal was accomplished on the (1 0 0) and (−1 0 0) planes to understand the mechanical properties of the crystal.
