Optically Induced Effects in Irradiated Ultrafine Al2O3–BeO Ceramics
We studied optically induced effects in ultrafine Al 2 O 3 –BeO ceramics irradiated with a high-dose pulsed electron beam (130 keV). Upon optical excitation of ceramics at 470 nm, optically stimulated luminescence is observed due to the depletion of traps associated with thermoluminescence peaks at...

–BeO ceramics irradiated with a high-dose pulsed electron beam (130 keV). Upon optical excitation of ceramics at 470 nm, optically stimulated luminescence is observed due to the depletion of traps associated with thermoluminescence peaks at 380 and 530 K. These traps are characterized by a complex energy spectrum with a nonuniformly distributed photoionization cross section. The prospects of using optically stimulated luminescence of Al
