摘要
Additively colored CaO crystals exhibit persistent phosphorescence over a broad band at 600 nm. This emission has been attributed to luminescence of F-centers in the crystals. Investigation of neutron-irradiated crystals, along with data from time-dependent luminescence, thermoluminescence, and infrared absorption spectra indicate that the luminescence is due to recombination emission at hydrogen impurity related trap sites in these crystals, and not to that of the F-center.
