✦ Synopsis

The nonlinear optical crystals of tris allylthiourea
cadmium chloride have been grown by temperature lowering solution
growth technique. Solubility of ATCC has been determined for
various temperatures. Meta stable zone width and induction period
values have been determined in order to optimize the growth
parameters. Nucleation parameters such as Interfacial tension,
critical radius and the free energy of formation of critical
nucleus have been evaluated. The as grown crystals were
characterized by the powder X-ray diffraction, UV-VIS absorption
and transmittance, FT-IR absorption, TGA-DTA, Dielectric and micro
hardness studies.
