摘要: Abstract Pure single crystals of Potassiumtetrakisthioureabromide (KTTB) were irradiated at room temperature with 40 MeV lithium ions fluences varying from 10 to 12  ions/cm 2 the 15 UD Pelletron facility Inter University Accelerator Centre (IUAC), New Delhi. The pristine as well KTTB characterized by photoluminescence under 2.8 eV blue excitation a He–Cd laser and UV–Vis absorption study radiation induced defects. ion-induced changes have also been studied respect their mechanical response using Vickers micro hardness technique. effect swift heavy ion beam on dielectric dispersion is explained in detail. Surface morphology was for crystals.
