The present study examines changes in the optical, structural, and dielectric properties of the crystals following irradiation and utilizes techniques such as UV-visible spectroscopy, atomic force microscopy (AFM), and scanning electron microscopy (SEM) to analyze the effects. The findings suggest modifications in optical absorbance, surface morphology, and structural integrity due to irradiation. Single crystals of ammonium penta borate (APB) were irradiated with 120 MeV Ag9+ swift heavy ions (SHI) of fluence 1×1013 ions/cm2. The UV-visible spectrum of irradiated crystal shows a slight shift in the absorption edge and it also indicates the non uniformity in its absorbance level. The AFM image confirms that the SHI-irradiated sample has a strong presence of raised tails and bulges. The surface roughness of the irradiated crystal is found to be several folds larger than the non-irradiated sample.
