摘要

The tremendous potential of organic–inorganic hybrid crystals in the next generation of optoelectronic and photonic technologies has led to a steady increase in their investigation recently. The semi-organic nonlinear optical single crystals of L-argininium perrhenate (LAPR) were grown with bulk size by employing the slow evaporation solution growth technique (SEST), and the crystal’s structural and physical properties were analyzed. The orthorhombic crystal structure of LAPR was revealed by the single-crystal XRD (SCXRD) method. The NMR spectral analysis was carried out for the title sample. The grown specimen of LAPR has been subjected to FTIR analysis to confirm the existing functional groups. The outcome of UV–Vis–NIR analysis reveals that the crystal has 80% transmittance and has a low cut-off wavelength, and these features confirm that the crystal could be useful for nonlinear optical applications. TG/DTA and DSC analyses have been used to reveal the thermal performance of the LAPR sample. The dielectric study was carried out for the LAPR sample crystal. The second harmonic generation (SHG) technique has been used to evaluate the SHG efficiency of LAPR. The crystal has a higher (3.1 times) SHG efficiency than the KDP crystal. From the laser damage threshold study, it is observed that the LAPR crystal has a high laser damage value, which confirms the suitability of optical device applications. The observed results of the LAPR single crystal suggest that the LAPR crystal could be a valuable prospect for NLO and optical applications.
