Abstract
Triglycine sulphophosphate (TGSP), chloroacetamide (AC) and 4-dimethylaminobenzaldehyde (DB) doped TGSP crystals were successfully grown from their respective aqueous solutions by slow cooling method. X-ray powder diffraction patterns were collected for pure, AC and DB doped TGSP crystals in order to determine their lattice parameter values. Fourier Transform Infra-Red (FTIR) spectroscopic analysis was carried out to confirm the molecular vibrations of TGSP and the presence of AC and DB in TGSP qualitatively. From the UV–Vis spectroscopic analysis, the absorption range was observed for the grown crystals. From the microhardness test, the Vickers’s hardness of the AC and DB doped TGSP crystals measured on (001) face was found to be higher than that of pure TGSP crystals. The dielectric studies showed the variation of dielectric constant as a function of frequency at room temperature. The thermal behavior of the pure and doped TGSP samples was studied from their thermogravimetric and differential thermal curves.
