Effect of oxygen ion irradiation on the structural and optical properties of L-arginine acetate single crystals

Abstract

In the present work, a potential nonlinear optical single crystal, L-arginine acetate (LAA) was grown by slow evaporation solution growth technique. The grown LAA single crystal was irradiated with oxygen ions at the dose rate of 600 krad and 1 Mrad in order to tune the structural and optical properties. The structural properties of pristine and oxygen ions irradiated LAA single crystals were studied using Powder X-ray diffraction and Fourier Transform Infrared spectroscopy. The results obtained reveal the structural changes that are generated due to irradiation. Optical behavior of prisitine and oxygen ions irradiated crystals was studied by UV-Vis-NIR and photoluminescence spectra recorded at room temperature.
