Abstract
Most irradiation studies in the hydrogen bonded ferroelectrics have been concentrated on the transient defects induced by ionising radiation such as UV light, where the defects are closely related to the optical properties. On the other hand, heavy ion beam irradiation effects have rarely been studied. Li3+ irradiations lead to the development of a well-defined surface H peak in dye doped KDP crystals. The stability of KDP single crystal was improved by doping organic dyes. The nano-islands of dye in KDP are likely to be dissolved and enhance the non-linear optical properties of these materials. The structural, optical and non-linear optical properties of the doped crystals were analyzed with the characterization studies such as powder XRD, UV-Visible and SHG measurements respectively. The results for doped KDP crystal are compared with the results of the pure KDP crystals.
