Growth and Characterization Studies of Potassium L-Alaninate NLO Single Crystal

Optical good quality defect free single crystals of Potassium L-alaninate (PLAla),  was grown by slow evaporation technique at room temperature. The physico-chemical properties of the as grown crystals were analysed from single crystal XRD, thermal, spectral,  and DC conductivity studies. From  XRD analysis, it is assured that Potassium L-alaninate (PLAla),  crystal belongs to orthorhombic system. Thermal studies shows their endothermic response to heat. The melting point, average weight loss and possibility of phase transition and decomposition of the material were determined by TG-DTA analyses. The FTIR analysis confirms the functional groups present in the crystal. UV-Visible transmittance spectra was recorded to identify the transparency in visible and near infrared (NIR) region.  The UV spectral studies show the good transparency of the crystals . The dielectric and AC conductivity studies were analysed as a function of resistance for various temperatures.  The result reveals that the crystal of  Potassium L-alaninate (PLAla) shows good AC electrical characteristics.
