Investigations on growth and characterization of glycine potassium iodide for non liner optical applications

Abstract Glycine Potassium Iodide (GPI) crystals have been grown using slow evaporation solution technique at room temperature. The functional groups and vibrational frequencies were identified using FTIR spectral analysis. The cell parameters were determined from single crystal X-ray diffraction analysis. The optical transmittance window and lower cutoff wavelength have been identified by UV-absorption spectrum analysis. The second harmonic generation (SHG) efficiency measurement was carried out by powder Kurtz method. The photoconductivity study confirms the positive photo conducting nature of grown crystal. The characterization studies have confirmed that the grown crystal is suitable for Non linear optical applications.
