Thiosemicarbazone of m-Nitrobenzaldehyde is an interesting organic crystal. It has been grown by slow evaporation solution growth technique (SESGT) using wood alcohol as solvent. The harvested crystals were purified by repeated recrystallization. The working groups of harvested crystals were examined by the Fourier Transform (FT-IR) spectral analysis. The UV-Visible Spectra are confirming the optical transparency. This is more helpful to use these crystals in electro optical applications. The harvested crystal Thiosemicarbazone of m-Nitrobenzaldehyde was characterized by proton nuclear magnetic resonance and of 13 C NMR spectra which show the molecular structure of the crystals. The TGA and DSC confirm the decay of the sample at 210oC. It further confirms the grown crystals Thiosemicarbazone of m-Nitrobenzaldehyde is thermally stable up to 210 o C. The second harmonic generation efficiency of the powdered Thiosemicarbazone of m-Nitrobenzaldehyde and was tested using Nd: YAG laser and it is found to be 5.6 times higher than that of urea.Copy Right, IJAR, 2019,.

Introduction:-Thiosemicarbazone of m-Nitrobenzaldehyde is an organic crystal plays a significant function in application in optical communication and optical computing devices. In recent year, an intense research work has been carried out to identify a special variety of thermally stable optical material. Organic compounds are often determined by very weak Vander walls and hydrogen bonds and possess a high degree of delocalization. Hence, they are optically more nonlinear than inorganic crystals. The growth methods depend on organic crystal size, hardness, physical body, and large nonlinear optical susceptibilities compared to the inorganic crystals.The slow evaporation solution growth Technique (SESGT) is an important technique because large size, stability, optical crystals are being created by this technique [1][2][3][4][5][6]. The harvested crystals were characterized by FT-IR, UV, 1H and 13C NMR, TGA-DSC, XRD, Micro hardness analysis, and SHG efficiency studied [7][8][9][10][11][12]. ExperimentalAn organic crystal of thiosemicarbazone of m-Nitrobenzaldehyde was prepared by adopting general procedure [13][14][15][16][17]. To a hot solution of Thiosemicarbazone in methanol, a solution of m-Nitrobenzaldehydein methanol was added drop wise during thirty minutes. The mixture was stirred and refluxed for 4 hours. It was filtered and the filtrate was concentrated to half the loudness. Later on a slow evaporation of the concentrate at room temperature,

“…Six glycine polymorphs have been extensively studied under high pressure conditions. 15 Glycine forms complexes with many organic and inorganic acids, which are prominent materials for nonlinear optical (NLO), piezoelectric, and ferroelectric applications, such as glycine phosphate, 16 triglycine sulfate, 17 triglycine selenate, 18 triglycine tetrafluoroberylate, 19 diglycine nitrate, 20 glycinium maleate, 21 glycinium oxalate, 22 glycine picrate, 23 bisglycinium oxalate, 24 glycine-phthalic acid, 25 and glycine-glutaric acid. 26 Among many glycine complexes, glycine phosphite (GPI) is a representative of a hydrogenbonded ferroelectric crystal.…”

Glycine phosphite single crystals were grown by employing the slow evaporation solution growth technique. Grown crystals were subjected to shock waves generated by a pressure-driven Reddy Tube. The (001) plane of the grown crystal was subjected to various numbers of shock pulses of Mach number 1.7 whereby its structural, optical, and morphological properties were investigated by using the powder X-ray diffractometer, ultraviolet (UV)-visible spectrometer, impedance analyzer, and optical microscope, respectively. The powder X-ray diffraction analysis confirms that the crystals have comparatively higher structural stability along the (001) direction. The observed UV-visible spectrum reveals a considerable increase in optical transmission when increasing the number of shock pulses. The band gap of the crystal is also found to have increased from 4.15 to 4.17 eV after the fifth shock-loaded condition. The dielectric behaviour of the crystal under shocked conditions is studied in the frequency range of 1 Hz to 1 MHz.

“…Picric acid is a highly oxidative, yellow crystalline solid, soluble in water, alcohol, chloroform, most organic solvents, and ether and the presence of three electron withdrawing nitro groups in the picric acid makes it as a good acceptor for neutral carrier donor molecule [14,15]. Picric acid has been combined with other amino acids to form various complexes and various studies on picrate-type crystals have been reported by many researchers [16][17][18][19][20]. Picric acid is an interesting inorganic matrix modifier due to its large dipole moment and its ability to form an extensive network of hydrogen bonds.…”

Potassium dihydrogen phosphate (KDP) crystal has been doped with picric acid to alter its physical and chemical properties. Picric acid doped KDP salt was synthesized by adding 2 mole% of picric acid into the aqueous solution of KDP. Using the synthesized salt of picric acid doped KDP and double distilled water, single crystals were grown by solution method with slow evaporation technique. The grown single crystal was subjected to XRD method to find the crystal structure. The functional groups of the sample were found by FTIR method. The elements in the picric acid doped KDP crystal were identified by EDAX and CHN analyses. SHG studies of the sample were done to check the second order NLO property. Dielectric studies for picric acid doped KDP crystal were carried out using a multi-frequency LCR meter. Thermal stability of the sample was found by TG/DTA studies. The microhardness of the sample was also measured at different applied low loads and the results obtained from the various studies are discussed.
