Synthesis, Growth and Optical, Electrical, Thermal Properties of L- Proline Adipate Single Crystals for Nonlinear Optical Applications

Optically good quality L-Proline Adipate (LPA) crystals have been grown by slow evaporation method. The cell parameters of the grown crystal were determined by single crystal X-ray diffraction technique. The band gap energies of the LPA single crystals have been calculated and their cut off frequencies was determined from UV-vis NIR spectral analysis. The dielectric behaviour of grown crystals has been studied in the frequency range from 50Hz to 5MHz. The thermal behaviours were identified by TG/DTA analyzes. The second harmonic generation (SHG) efficiency was studied by using Kurtz powder technique.
