Single crystals of an organic nonlinear optical (NLO) material, glycine picrate (DGP) has been grown from mixed solution by using the novel uniaxial crystal growth method of Sankaranarayanan and Ramasamy (SR) and conventional method. The novel method allows the crystal to grow in one specified axis with well developed faces. The grown crystals have been subjected to crystal structure studies and characterized by single crystal X-ray diffraction, Powder X-ray diffraction (PXRD), UV-Vis spectroscopy, Fourier transform infrared spectroscopy (FTIR), Thermogravimetric/differential thermal analysis (TG/DTA), Vickers microhardness, dielectric measurements, etching and High-resolution x-ray diffraction (HRXRD). The NLO efficiency of the crystal has been confirmed by using the Kurtz powder technique. The present study indicates that the SR method is superior to conventional method for the growth of DGP single crystals.

“…The introduction of dichroic beam splitters by Brumberg in 1948, and their subsequent commercialization by Ploem in 1967, improved the efficiency of the beam splitter to nearly 100% and further improved the filtering effect of the microscope. Epifluorescence study reveals that MMTG emits green light 21 and fluoresces is at about 545 nm confirming its suitability for NLO applications. The fluorescent image thus obtained is shown in Figure 7.…”

The design and synthesis of organic nonlinear optical (NLO) crystals are a promising area of current research in materials science. Organic materials are found to possess better non linear optical properties when compared to inorganic materials. Recently, there has been a widespread interest in the metal-organic coordination compounds, which are a combination of metal and organic ligands, having exciting NLO properties. Non-linear optical single crystals of Manganese mercury thiocyanate glycol monomethyl ether(MMTG) were grown from a mixed solvent of glycol monomethyl ether and water by slow evaporation method. Optimum conditions for the growth at ambient temperature were found by investigating different growth parameters. The percentage of optical transmittance by the grown crystal was ascertained by a UV-visible spectral study. The growth features of MMTG crystal was observed by Field Emission Scanning Electron Microscopy technique and Epifluorescence studies for the same were carried out for the first time thus revealing the excitation of the sample around 545 nm. Dielectric measurements on MMTG single crystal were carried out for various frequencies at different temperatures.

“…The dielectric constant ε' of Cu 2+ :MHMH single crystal at different temperatures 308K, 323K, 343K, 363K and 383K with frequency range 50 Hz to 1 MHz was presented in Figure 1. It was evident from the Figure 1 that the dielectric constant decreases with increase in frequency [6][7][8][9][10]. Also, the frequency dependence of dielectric constant ε' at different temperatures showed that at high frequencies the dielectric constant values were almost independent of temperature but as the frequency decreases the dielectric constant was more temperature dependent.…”

The dielectric and thermal analysis of copper doped Magnesium Hydrogen Maleate Hexahydrate single crystals are studied for the first time. The dielectric constant, loss tangent, a.c. conductivity and a.c. activation energy were measured with variation of frequency in the range 50 Hz to 1 MHz. Dielectric studies reveal that the present crystal under investigation show good optical quality. The melting point and final compound after decomposition were determined using the DTA/TG analysis.
