Triglycine sulfate (TGS) crystals, with or without sodium bromide (NaBr) doping, were grown from aqueous solutions by slow evaporation method. The structural characterization was carried out by single crystal XRD method and found that all the grown crystals crystallize in monoclinic structure. The pure and NaBr doped TGS crystals were also subjected to microhardness, dielectric studies, measurement of density and atomic absorption spectroscopic studies.Keywords

Single crystals of Triglycine Sulfate (TGS) were grown in water and also were grown in water-soluble CdS nanoparticles dispersed in water by solution method with slow evaporation technique at room temperature. Watersoluble CdS nanoparticles were synthesized by microwave-assisted solution method using the precursors such as cadmium sulfate, thioglycolic acid and ethylene diamine and they were used for the growth of CdS-added TGS crystals. The grown crystals were characterized by XRD technique, UV-visible spectral studies, measurement of density, microhardness studies, atomic absorptions studies. The effect of Cd2+ ions on various properties of TGS crystals have been analyszed and reported.Keywords
