Investigation on certain optical, thermal, and Z-scan studies of nonlinear optical tris–sarcosine calcium chloride single crystal

Slow solvent evaporation was used to produce single crystals of Tris–Sarcosine Calcium Chloride (TSCC) from aqueous solution. The cell parameters of the grown crystals were determined using the single-crystal X-ray diffraction analysis. The existence of functional groups in TSCC was confirmed using the Fourier Transform Infrared spectrum analysis. Energy-Dispersive X-ray Analysis verified the chemical composition of the TSCC crystal. The optical transmittance of TSCC was greater than 90%, according to the UV–Vis–NIR transmittance spectrum measurements. This indicates TSCC is an appropriate material for NLO applications. The optical characteristics of the grown crystal, including band gap energy, were determined. The photoluminescence characteristics of TSCC crystal were also studied in order to better understand its optical device manufacturing. The thermal behavior of TSCC was investigated using the TGA/DTA and DSC studies. For various temperatures, the fluctuation of the dielectric constant and dielectric loss with regard to frequency variation was examined and the results were described in depth. The TSCC susceptibility χ(3) and nonlinear refractive index n2 values were evaluated. The saturation absorption of TSCC was revealed by open aperture Z-scan technique, and the self-defocusing performance was revealed by closed aperture Z-scan measurements.
