چکیده انگلیسی
Optical absorption, thermoluminescence (TL), and stationary and time-resolved spectra of X-ray luminescence (XL) and cathodic luminescence (CL) in anion-defective αâAl2O3 crystals have been studied. It was found that the XL and CL spectra were dominated by the luminescence of F+-centers over the nanosecond interval, Ali+â and Ti3+-centers over the microsecond interval, and F- and Cr3+-centers over the millisecond interval of the relaxation time. It was shown that the luminescence of F+-centers made the decisive contribution to the released energy at the first stage of relaxation. The CL light sum illuminated in the F-band correlated with the TL yield in radiation detectors based on αâAl2O3.
