Nucleation kinetics, solubility, growth and characterization of novel semiorganic crystal—Bisthiourea zinc formate

Single crystals of bisthiourea zinc formate were grown by the low temperature solution growth technique. The nucleation parameters such as solubility, induction period, interfacial energy and metastable zone width, radius of critical nucleus, critical free energy barrier, number of molecules in the critical nucleus and energy per unit volume have been evaluated. Metastable and induction period values were determined experimentally in order to optimize the growth parameters. Transparent good quality single crystals are characterized by single crystal XRD, powder XRD and FTIR analysis. Optical and photoluminescence studies have been carried out for the grown crystal. The results have been discussed in detail.
