Investigation of nucleation parameters and third order nonlinear optical properties of triglycine sodium molybdate single crystals

In this paper, nucleation parameters such as induction period, interfacial tension,
metastable zone width, radius of critical nucleus and Gibbs free energy change in solution-
grown triglycine sodium molybdate (TGSM) single crystals are studied. The solubility of
TGSM at different temperatures has been determined. The induction period and metastable
zone width have been experimentally found for optimizing the growth process. Various
critical nucleation parameters have been calculated from the experimentally obtained values
based on the classical nucleation theory. The nucleation rate is found to increase with the
growth of the supersaturation value. The third order non-linear parameters such as
absorption coefficient (β), susceptibility (χ (3) ) and refractive index (n 2 ) obtained from the
Z-scan analysis confirm the self focusing and reverse saturation absorption nature of the
grown crystals.
Keywords: nonlinear interfacial tension, nucleation, optics, supersaturation.
