Abstract

Organic nonlinear optical crystal dimethyl-amino-pyridinium-4- nitrophenolate-4-nitro-phenol was subjected to 100 MeV Ag⁸⁺ ions and 50 MeV Si⁸⁺ ions. The radiation effects are studied in terms of processes observed with the pristine samples and in comparison with them. The dielectric properties of the crystals were studied before and after irradiation from 100 Hz to 5 MHz at various temperatures (308-383 K). A drastic increase in the dielectric constant is seen due to irradiation. The dielectric constant and conductivity increases with the increase of irradiation fluence for the samples. The observed results are discussed in detail.
