“…The large second endothermic peak appeared between 2068C and 2188C, and indicates the complete decomposition of LLyTCA crystals. This study reveals that the crystal is chemically stable up Torsional vibration of CÀ ÀC structure to 2068C, which is comparable to that of L-histidinium trichloroacetate (2108C) [27,28].…”

Single crystal X-ray diffraction analysis was carried out on a new nonlinear optical L-lysinium trichloroacetate single crystal. The crystals were obtained from the combination of aqueous solutions of trichloroacetic acid and L-lysine by slow evaporation. A vibrational spectrum of the crystal was determined using FTIR analysis. Differential scanning calorimetry was used to determine the thermal stability of the compound. UV -vis -NIR spectrum of the compound gives its optical transparency. Powder SHG efficiency of L-lysinium trichloroacetate was also studied using Kurtz-Perry powder SHG measurement.

In this work, uranine-dyed zinc (tris) thiourea sulfate (ZTS) monocrystals, 26 mm×15 mm×10 mm in size, were synthesized by the solution method at ambient temperature. Their purity, crystallinity, lattice parameters, and functional modes were studied by x-ray diffraction, Fourier transform-infrared spectroscopy (FT-IR), and FT-Raman spectroscopy analyses. The sodium ion content of the crystals from the dye was confirmed by elemental analysis. The diffused reflectance spectral analysis of the dyed crystal revealed a characteristic absorption band at 490 nm attributed to the presence of the dye. The calculated band gaps of the non-dyed and dyed crystals were 4.53 and 4.57 eV, respectively. A green emission peak at ∼ (512 ± 4) nm was observed in the photoluminescence spectrum of the uranine-dyed crystals. A differential scanning calorimetry study confirmed that the thermal stability improved owing to the addition of the dye. Dielectric and microhardness studies were conducted to examine the significant improvements in the corresponding properties of dyed crystals. The results demonstrated the competency of the dyed ZTS crystals for applications in optoelectronic devices.

“…Slight improvement in the thermal stability is attributed to the deuteration effect of L-alanine. The thermal strength of the compound is comparable to L-histidinium trichloro acetate (251 1C) [20] and L-threonine of 265 1C [21].…”
