Synthesis and Characterization of Non-Linear Optical Crystal of Manganese Mercury Thiocyanate Glycol Monomethyl Ether

Abstract

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.
