摘要

Sulphamic acid magnesium chloride is a nonlinear optical crystal which has been effectively grown through low-temperature slow evaporation solution growth method. X-ray diffraction (XRD) analysis suggests that the grown crystal exhibits a tetragonal structure. The crystal of sulphuric acid magnesium chloride had various functional groups, based on FTIR spectroscopic investigation. The UV–visible spectrum was used to confirm the optical properties of the crystal. Differential scanning calorimetry was used to estimate the melting point, and thermogravimetric analysis was used to ascertain the developed crystal’s heat sensitivity. The grown crystal dielectric characteristics at different temperatures, like dielectric constant and dielectric loss, were studied. The fluorescence emission spectrum shows that the emission peak occurs at a wavelength of 543 nm. Using photoluminescence study, the emission peak wavelength was determined. Kurtz–Perry powder and Z-scan techniques were used to study the nonlinear optical property.
