- Abstract
Lithium sulphamate single crystals have been grown by the slow evaporation solution growth method and were analyzed via various spectroscopic techniques to assess their structural and optical properties. The grown crystal ingot was first subjected to powder-X-ray diffraction and FT-IR to determine its structural parameters. Raman spectroscopic analysis was also carried out to describe the corresponding Raman bands assignments of grown crystal. The transmittance percentage of the crystal was thoroughly investigated by UV–vis spectroscopy and the bandgap was calculated using the Tauc's plot. Further, photoluminescence spectroscopy determined the emission spectrum, and the decay rate was observed by the time-resolved photoluminescence. In addition, the Z-scan technique further examined the nonlinear optical behavior of the titled crystal. The THz spectroscopy was also performed to analyze its absorbance behavior in the THz region. The thermal characteristics of the crystal were examined by DSC and TGA/ DTA analysis.
