“…[19][20][21][22] Especially, several studies have been attempted with different organic and inorganic dopants to carry out effective internal bias to stabilize the domains and desired pyroelectric and ferroelectric properties of triglycine sulfate crystals to overcome the depolarized by the applied fields. [23,24] Some of the oxalate-based single crystals such as sodium hydrogen oxalate monohydrate, potassium hydrogen oxalate monohydrate, and l-valine doped potassium hydrogen oxalate have been reported for NLO applications. [25][26][27][28] In addition, the growth of glycine and bisglycine oxalate crystals was characterized by structural, optical, thermal, electrical, etc., based on the importance of the nonlinear property.…”

Triglycine oxalate single crystal is grown by a slow evaporation technique from the saturated solution at the predetermined temperature. X‐ray diffraction studies of the grown crystal reveal that the grown crystal belongs to a monoclinic structure. The presence of elements and various functional groups of the triglycine oxalate is found in the Fourier transform infrared analysis. Optical transparency of the grown crystals is found to have the maximum transparency in the entire visible region. Thermogravimetric analysis shows that the grown crystals have three stages of decomposition. The microhardness of the grown crystals exhibits that the crystal is a soft material. The electrical studies such as dielectric constant, and dielectric loss are determined for the frequency range from 100 Hz to 200 kHz at different temperatures.

“…However, this polarity can be reoriented or reversed fully or partially through the application of an electric eld with ferroelectric materials [4]. Hence, these crystals have several practical applications in developing capacitors, nonvolatile memory, electro-optic materials for data storage applications, light de ectors, high-performance gate insulators, modulators, displays, etc [5]. Amino acids are strong applicants for optical second harmonic generation (SHG) because they contain chiral carbon atoms and crystallize in noncentrosymmetric space groups [6].…”

“…Alkali metal chloride compounds are very important to modify the properties of TGS single crystals [13]. Single crystals of TGS [3], barium-doped TGS [5], sulfuric acid-doped TGS [16], glycine copper nitrate [17], and glycine glycinium picrate [18] have been reported by using the slow evaporation solution growth method.…”

Triglycine sulphate (TGS) and 1 and 2 mol% of magnesium chloride-doped TGS single crystals have been grown by using the slow evaporation solution method at room temperature. Pure and magnesium chloride-doped triglycine sulphate single crystals in a dimension of 12 × 12 × 5 cm3 have been grown at room temperature. The grown samples have been investigated by various characterization techniques such as single crystal X-ray diffraction, UV-VIS/NIR spectroscopy, dielectric studies, and energy dispersive X-ray analysis (EDAX). The single crystal X-ray diffraction studies revealed that both 1 and 2 mol% of MgCl2-doped TGS single crystals have been crystallized in monoclinic crystal structure with space group P21/m. The UV-VI/NIR spectra analysis confirmed that both pure and 1 and 2 mol% of MgCl2-doped TGS single crystals have wide optical transparency in the wavelength range of 236–1100 nm. The bandgap energy of both samples has been found to be 5.25 eV. The dielectric properties of the grown samples were recorded by measuring the dielectric constant as a function of temperature from 45 to 55°C with various frequencies (100 Hz – 1 MHz). The dielectric studies revealed that the dielectric constants of 1 and 2 mol% of MgCl2-doped TGS single crystals were increased with decreasing frequency and that the transition temperature was found to be 51°C. The EDAX spectrum confirmed the incorporation of MgCl2 into TGS single crystals.

Aim: To study the temperature stability of TGS doped with ZnSO4, CdCl2, BaCl2, and compare it with that of pure TGS. Objectives: Synthesizing pure and doped TGS and studying their temperature dependence using TGA, DTA, and DSC analysis. Methods: Slow cooling solution growth is used to grow single crystals of pure and doped TGS. The TGA, DTA and DSC analysis is conducted for determining the temperature stability. Results: The thermal analysis of pure and doped TGS shows that the doped samples show a similar dependence on temperature as pure TGS. The temperature of decomposition of pure and doped samples ( BTGS, ZTGS, CdTGS) is 226.60°C, 228.38 °C, 229.13 °C, and 239.13 ° C respectively. The melting onset of these samples is 214.51 ° C, 216.04 ° C, 217.69 °C and 216.04 ° C respectively. Conclusion: The study shows that doping TGS with the above three described materials did not alter their temperature stability considerably. It is a good result as doping TGS, for varying its characteristics like absorbance, reflectance, bandgap energy, etc., did not alter its temperature stability. Therefore TGS doped with the above three dopants can be used at the same temperature ranges as of pure TGS but with much-improved efficiency.
