Abstract:

Undoped and L-tartaric acid doped Triglycine Sulpho-phosphate(TGSP) salts were synthesized and single crystals of TGSP were grown by slow evaporation technique. Solubility of the samples for various temperatures in the range 30-50 oC.  It is observed that solubility in water increases with temperature for the samples, showing the positive temperature coefficient. Bulk crystals have been grown from the aqueous solutions of undoped and L-tartaric acid doped Triglycine Sulpho-phosphate.  Single crystal XRD studies on the grown crystals  reveal  the monoclinic crystal structure. Mechanical  parameters such as hardness, stiffness constant and yield strength were evaluated. Dielectric studies were performed to ascertain the ferroelectric nature of the samples. SHG and LDT studies reveal the NLO properties of the samples.
