Infrared (IR) stimulated luminescence from α Al 2 O 3 :C single crystals was investigated. The data show that the IR-stimulated luminescence curve contains at least two overlapping signals. One of the components was found to be both thermally and optically unstable whereas the second component was thermally stable and slowly decaying under constant stimulation. The slow decaying component...
In BeO ceramics, exposed to ionizing radiation, an intense OSL signal was observed. The properties of the signal and its behavior under various experimental conditions were investigated. It was found that the OSL signal is a composite signal and exhibits strong thermal quenching. The quenching energy was estimated as ~0.5eV. The excitation spectrum of the OSL signal was obtained as a broad peak in...
