Studies on Growth and Various Properties of Triglycine Sulfate (TGS) Crystals Doped with Copper Sulphate

Abstract

Pure and copper sulpahte-doped Triglycine Sulfate(TGS) salts were synthesized and single crystals  of the synthesized salts were grown from aqueous solutions by slow evaporation technique.  The  structural studies on the grown crystals were carried out by  single crystal XRD analysis and found that the grown crystals crystallize in monoclinic structure. The FTIR spectra have been recorded in the range 500-4000 cm^-1  and   the functional groups  of the grown crystals have been identified.  UV-Visible   spectra show that the grown crystals have wide optical transparency in the entire visible region. Atomic absorption study reveals the presence of copper  in  the doped TGS crystals.   Density of the samples have been measured by floatation method. The dielectric  studies  for the pure and copper sulphate-doped TGS crystals  have been performed by measuring the dielectric parameters like dielectric constant  and dielectric loss  at a constant frequency of 1000 Hz  with the  temperatures ranging from 30  to  75 ^oC  and this study reveals an increase of dielectric constant and loss when TGS crystal  is doped with copper sulphate.  Microhardness  studies have been carried out  to analyse  the mechanical strength of the samples.
