Effect of 100keV N+ Ion Irradiation on Semi-Organic Single Crystal of L-Arginine Phosphate Monohydrate Single Crystal for Nonlinear Optical Applications

The potential Semi-organic nonlinear optical material of L-Arginine phosphate monohydrate (LAP) single crystal has been grown by slow evaporation solution growth technique using water as the solvent. The well prepared single crystals of pure LAP were irradiated at room temperature with 100 keV Nitrogen (N+) ions at uence of 1x1016, 5x1016 and 1x1017 ions/cm2. The pure and irradiated LAP single crystals were characterized by different characterization technique. The structural changes were analyzed by means of powder X-ray diraction analysis. The functional groups of the pure and irradiated compound have been identified by FTIR. The photoluminescence and UV-Vis. absorption were done at room temperature and found that there is insignificant absorption in entire visible region. Vickers microhardness technique was used to study effect on mechanical strength of crystal at different ion fluencies. The surface studies of the grown and irradiated single crystal were done by using the optical microscope and found that roughness of surface increases with increasing ion fluencies.
