Abstract :

Some organic materials exhibit exceeding by large amount of nonlinear property and they are found to be more suitable for device faications. Hence, in the present study Glycine doped with Potassium Iodide (GLPOI) an organic material, has been extensively studied with regard to the growth and various properties. Single crystals of Glycine doped with Potassium Iodide (GLPOI) with good degree of transparency were grown from aqueous solution by slow evaporation technique. Single crystal X–ray diffraction analysis reveals that the crystal belongs to hexagonal system. Some fundamental data such as valence electron, plasma energy, Penn gap, Fermi energy and electronic polarizability of the grown crystal were calculated. The optical absorption studies show that the crystal is transparent in the entire visible region with a cut off wavelength of 311 nm. The optical band gap energy was found to be 3.99 eV. The dependence of the extinction coefficient (K) and refractive index (n) on wavelength has also been reported. Dielectric constant measurements were carried out at different temperatures and frequencies.
