摘要：
The characteristics of the photoluminescence and electron paramagnetic resonance CESR) spectra of stoichiometric MgAl2O4 spinel specimens irradiated in FFTF-MOTA at temperatures between 385 degrees C and 750 degrees C to fluences ranging from 5.3 to 24.9 x 10(26) nm(-2) are measured. Photoluminescence spectra show a complex behaviour associated with the presence of an active defect with different surroundings. The EPR spectra show two different bands that are associated with different defects. (C) 1998 Elsevier Science B.V. All rights reserved.
