Radiation induced recharging of cerium ions in Nd, Ce:Y 3Al 5O 12 single crystals
Abstract
Radiation induced recharging of Ce 3+ and Ce 4+ ions in Ce and Nd doped yttrium-aluminium garnet crystals was observed. This effect depends on the Ce 3+ ion concentration and the type of ionizing radiation. The crystals investigated were irradiated with gamma-rays, protons with fluences up to 10 14 protons/cm 2 and electrons with a fluence of 5 × 10 16electrons/cm 2. Changes in cerium concentration after gamma-irradiation were calculated from the formula of Smakula.
