摘要

Succinic acid sodium bisulfate (SASS) single crystals were grown successfully using a slow evaporation method in aqueous solution under ambient conditions. The resulting crystals were of high optical quality and exhibited noteworthy third-order nonlinear optical (NLO) behavior. Structural characterization through single-crystal X-ray diffraction confirmed that the crystals adopt a monoclinic lattice, with detailed space group identification achieved via refinement analysis. The functional integrity of the compound and the coordination within its lattice were verified using Fourier Transform-Infra Red spectroscopy, which revealed the presence of characteristic vibrational modes. UV–Vis spectroscopy indicated strong optical transparency in the visible region, with a distinct absorption edge at 231 nm corresponding to a large band gap of 5.36 eV, suggesting the material’s potential for use in optoelectronic and ultraviolet filtering devices. The mechanical strength of the SASS crystals was assessed through Vickers microhardness testing, from which essential parameters such as the hardness value (Hv), work hardening coefficient (n), yield strength (σy), and stiffness constant (C₁₁) were determined, reflecting solid mechanical integrity. Elemental analysis via Energy-Dispersive X-ray Spectroscopy (EDAX) confirmed the expected composition of the material. The third-order NLO response was further evaluated using the open-aperture Z-scan method, employing a nanosecond-pulsed Nd:YAG laser. From this, the nonlinear absorption coefficient β = 6.90 × 102 mW−1, nonlinear refractive index n₂ = 3.154 × 104 W/m2, and both real and imaginary components of the third-order susceptibility χ⁽3⁾ = 1.644 × 10–9 esu were calculated. These comprehensive findings highlight the applicability of SASS crystals in next-generation photonic and optoelectronic technologies.
