Luminescence and defect studies of YAlO3:Dy3+, Sm3+ single crystals exposed to 100Â MeV Si7+ ion beam

► IL, PL and TL spectra for Sm3+ and Dy3+ activated YAlO3 single crystals reported. ► Influence of 100 MeV Si7+ ion influence on luminescence properties reported. ► From TL glow peaks trapping parameters were evaluated and discussed.
