“…Therefore, polarization can occur only by the movement of electronic charges rather than the movement of ions, resulting in a low dielectric constant. Electronic and space charge polarization predominantly in the low-frequency region suggest that the as-grown crystal possesses an enhanced optical quality with fewer defects, and this phenomenon is an essential characteristic for nonlinear optical applications [18][19][20]. As shown in Fig.…”

Synthesis, growth, and structural, optical, mechanical, electrical properties of a new inorganic nonlinear optical crystal: Sodium manganese tetrachloride (SMTC), J. Taibah Univ. Sci. (2015), http://dx. AbstractA new inorganic nonlinear optical single crystal of sodium manganese tetrachloride (SMTC) has been successfully grown from aqueous solution using the slow evaporation technique at room temperature. The crystals obtained using the aforementioned method were characterized using different techniques. The crystalline nature of the as-grown crystal of SMTC was analyzed using powder X-ray diffraction. Single-crystal X-ray diffraction revealed that the crystal belongs to an orthorhombic system with noncentrosymmetric space group Pbam. The optical transmission study of the SMTC crystal revealed high transmittance in the entire UV-vis region, and the lower cut-off wavelength was determined to be 240 nm. The mechanical strength of the as-grown crystal was estimated using the Vickers microhardness test. The second harmonic generation (SHG) efficiency of the crystal was measured using Kurtz's powder technique, which indicated that the crystal has a nonlinear optical (NLO) efficiency that is 1.32 times greater than that of KDP. The dielectric constant and dielectric loss of the compound were measured at different temperatures with varying frequencies. The photoconductivity study confirmed that the title compound possesses a negative photoconducting nature. The growth mechanism and surface features of the as-grown crystals were investigated using chemical etching analysis.

“…[2]. In the past years, many authors have reported the growth and various characterizations of γ-glycine with various additives, such as phosphoric acid, potassium chloride, potassium fluoride, lithium sulphate, lithium acetate and lithium nitrate [3][4][5][6]. Gamma glycine is currently grown by many conventional methods, such as slow cooling, slow evaporation as well as gel method.…”

A single crystal of gamma-glycine (GG), a polymorph of glycine, was synthesized by crystallization. The single crystal of GG was grown from an aqueous solution. The morphology of GG was studied in order to assess its growth facets. The good quality single crystals were subjected to X-ray diffraction studies to reveal their structure. The FT-IR spectral analysis was carried out to confirm the presence of expected functional groups. The UV-Vis analysis was done for GG single crystals to determine the optical transparency and band gap. Simultaneous TG-DTA analysis was employed to understand the thermal and physicochemical stability of the title compound. The mechanical stability and laser stability of GG single crystal were studied using Vickers microhardness test and laser induced damage threshold on different planes of the crystal to reveal its anisotropic nature. The dielectric measurement was carried out as a function of frequency and the results were discussed. The existence of second harmonic generation (SHG) of the title compound was confirmed by Kurtz-Perry powder technique. The SHG effective nonlinearity and particle size dependence of GG powder sample were compared with a standard reference material: potassium dihydrogen phosphate (KDP).

“…The resulting residue gives a weight loss for a wide range of temperature between 213.95 • C and 763.65 • C. The weight loss corresponds to 3.422% and 0.088 mg of residue remains. Hence, it can be useful for making the NLO devices below its decomposition temperature [21].…”
