Synthesis, Growth and Nucleation Kinetics of Potassium Hydrogen Oxalate Hydrate Single Crystal (C4H3KO82H2O) - A Third Order Nonlinear Material

Slow evaporation method was used to develop the metal organic compound of potassium hydrogen oxalate hydrate. The crystal system and lattice constant of the developed compound were analyzed with the help of single crystal X-ray diffraction technique. For diverse temperature, the nucleation curve and solubility of the compound were calculated experimentally. The solubility curve showed that the compound exhibit a positive temperature gradient of solubility. Various parameters for growth kinetics such as free energy change, induction period, nucleation rate were evaluated experimentally. The semiconductor laser of wavelength 532 nm was utilized in the Z-scan method to determine different nonlinear parameters like third-order refractive index, susceptibility and absorption coefficient.
