Growth and characterization of l-glutamic acid and sodium sulphate doped tri glycine sulphate single crystal

• We have grown single crystals of l-glutamic acid and sodium sulphate doped tri glycine sulphate.
• The phase transition temperature of the doped crystals is increased to 50 °C.
• Dielectric constant is seen to improve with increase in dopant concentration.
• Optical cut off wavelength is 235 nm.
• PE loop measurement shows improved residual polarization.

Single crystal of tri glycine sulphate has been grown in the presence and absence of l-glutamic acid and sodium sulphate by slow evaporation growth. The grown crystal was analyzed by single crystal X-ray diffraction. FTIR studies were used to confirm the presence of functional groups present in the grown crystals. The optical absorbance studies show the cut off wavelength to be 235 nm. The phase transition temperature was found to be 50 °C from DSC analysis. The dielectric behavior was identified. The AC conductance of the grown crystal was plotted. PE loop measurement is taken.
