Ionoluminescence and photoluminescence in swift heavy ion-irradiated Al2SiO5 [PDF]

Radiation Measurements, 2003
Abstract Ionoluminescence (IL) and photoluminescence (PL) of aluminum silicates irradiated with 100 MeV swift Ni+8 ions with fluences in the range 7.5×1010– 1.0×10 14 ions / cm 2 have been studied. A pair of IL bands with peaks at ∼775 and 875 nm are recorded in both natural crystalline and pelletized kyanite ...
