摘要: Abstract We have assessed the feasibility of carrying out time- and wavelength-resolved laser-induced fluorescence measurements radiation damage in glassy silica. The consequences alpha decay Es-253 LaPO4 nanophases embedded silica were probed based on excitation 5f states Cm3+, Bk3+, Es3+ ions. recorded emission spectra luminescence decays showed that ejected Bk-249 daughter ions into surrounding created within nanophases. This conclusion is consistent with predictions an ion transport code commonly used to model implantation. Luminescence from 6D7/2 state Cm3+was as internal standard. Ion–ion energy transfer dominated dynamics observed emitting strongly influenced intensity spectra. In appropriate sample materials, provides a powerful method for fundamental investigation alpha-induced
