Synthesis, growth and characterization of magnesium sulphamate – A promising non-linear optical crystal

Jaishree, D ; Kanchana, G ; Kesavasamy, R


Single crystals of magnesium sulphamate, a promising non-linear optical crystal were synthesized and grown from aqueous solution by slow evaporation method at room temperature. The powder X-ray diffraction and single crystal X-ray diffraction analysis confirmed the formation of new crystal. The crystals were characterized by energy dispersive X-ray analysis (EDAX) to reveal their chemical composition. The functional groups were analyzed by FT-IR and FT-Raman techniques. The optical transmission region was analyzed by UV-Vis-NIR studies. Thermogravimetric analysis (TGA) and differential scanning calorimetric (DSC) studies showed the thermal behaviour of the grown crystal. The non-linear optical (NLO) property of the crystal was tested by Nd-YAG laser as a source.
