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. [ABSTRACT FROM AUTHOR]

The crystal of zinc potassium aluminum sulphate nonadecahydrate (ZPASDH) was first time grown by the slow evaporation method.

In recent years, nonlinear optical materials have received attention due to their potential applications in photonics and opto‐electronics. In this pursuit, lithium sodium sulfate (LSS) single crystals are synthesized by adopting a slow evaporation technique at constant temperature (40 °C). The single‐crystal X‐ray diffractometer (XRD) study confirms that the grown LSS belongs to trigonal symmetry with the lattice parameters a = b = 8.452 Å, and c = 30.27 Å. The crystalline nature and purity of LSS are confirmed by the powder XRD technique. The lower cutoff wavelength and optical bandgap of the grown crystal are determined using transmission spectra and found to be 335 nm and 3.5 eV, respectively. The photoluminescence spectrum of the crystal shows the strong blue/green emission at 510 nm, which explains the second harmonic generation (SHG) property. The SHG efficiency is confirmed by the Kurtz and Perry powder method and the SHG efficiency of LSS is 1.09 times greater than that of pottasium dihydrogen phosphate (KDP). Thermal parameters of the titled material are calculated using a thermogravimetric (TG)/differential thermal analysis (DTA) analyzer. Microhardness studies and the diamagnetic nature of LSS are carried out using a Vicker's hardness tester and a vibration sample magnetometer. An attempt is made to grow a lithium sodium sulfate (LSS) inorganic single crystals due to its higher optical quality and mechanical stability (up to 270 kg mm−2). Prominent thermal stability is also observed as the melting point of the crystal is 521.4 °C. Due to these potential properties, LSS can be employed as an efficient candidate for optoelectronic device fabrication.. [ABSTRACT FROM AUTHOR]
