The single crystal of 2-amino-5-nitropyridinium chloride (2A5NPCl) was developed using the assembled temperature reduction (ATR) technique and a slow evaporation solution. The crystal was cut for irradiation as it was growing. Cesium sputtering was used to choose a swift heavy ion (SHI) of Au3+ from a source of negative ions (SNICS). Au3+ ions of (1013, 5 x1013, and 1014 ions/cm2) different fluence irradiated on the semi-organic samples. A luminescence study reveals that intensity decreased due to the loss of luminescence property of the material, which is caused by swift heavy ions (SHI). The formation of intermediate energy levels which converted the photon into phonon affected the radiative transition. Hence, the peak shifted and the intensity of the peak decreased. More ions were activated with lattice disorders at higher fluences, which boosted the activation of ion interactions. Capacitance increased due to this interaction of ions hence dielectric constant increased as increased the ion fluence 1013 ions/cm2 through 1014 ions/cm2. When a semi-organic 2-amino-5-nitropyridinium chloride (2A5NPCl) was exposed to high fluence radiation, pores, cracks, and roughness could all be clearly visible in the SEM along with the material's roughness. SHI significantly changed the surface of 2-amino-5-nitropyridinium chloride (2A5NPCl) at higher fluence. When compared to pristine, it was determined that the non-centro symmetric system in 2-amino-5-nitropyridinium chloride (2A5NPCl) was less impacted than in the other derivatives of the 2-amino-5-nitropyridinium families of crystals. Irradiated crystals' nonlinear optical properties were less than pristine; however, they were still higher than reference material KDP. [ABSTRACT FROM AUTHOR] |
