Abstract:

Temperature quenching of the photoluminescence at 3.0-eV (F-centers) and 3.8-eV (F+ -centers) in alpha-Al2O3 single crystals after a photothermal treatment was studied. Manifestation of the compensation effect, which is related to a consistent change of quenching parameters, was revealed. The isokinetic temperatures T-i were calculated to be equal to 384K (3.0-eV emission) and 394K (3.8-eV emission). The difference T-i = 10 K corresponded to temperature shift between thermoluminescence maximums at the emission bands under discussion. (c) 2006 Elsevier B.V. All rights reserved.
