ABSTRACT. Effect of Sulphuric acid (H2SO4) addition on the growth of triglycine phosphate (TGP) crystal has been studied from the aqueous solution by slow evaporation technique. The characteristics absorption bands of pure and H2SO4 admixtured TGP crystals are confirmed by FTIR spectra. UV-visible transmittance spectra were recorded for the samples to analyze the transparency of the grown crystals. The composition of pure and doped TGP crystals have been confirmed by EDAX analysis. The dielectric constants of the crystals have been studied and result suggests that the H2SO4 is doped into TGP crystal and that the doping increases its dielectric parameters.

Keywords: TGP; NLO; PXRD: FTIR; EDAX; UV;TGA/DTA.
