Abstract: Pure and Ni2+ added glycine sodium sulfate (GSS) single crystals were grown by the slow evaporation technique and characterized chemically, structurally, thermally, optically, mechanically and electrically. Effect of Ni2+ addition as an impurity on the properties of GSS has also been investigated. All the six crystals grown exhibit normal dielectric behavior and are found to be thermally stable up to 250°C, NLO active and mechanically soft. The Ni2+ addition is found to increase the dielectric parameters. The low dielectric constant values observed for pure GSS indicate that GSS is not only a promising NLO material but also a low dielectric constant value dielectric material.
