Abstract:

Thin-layer material based on nanostructured Al2O3 of the surface density 5 mg/cm(2) was obtained. The material is characterized by high OSL and TL yields comparable with those for TLD-500 which is one of the leaders among the TL and OSL detectors. The dose response, fading and dependence of 11 yield on heating rate was studied. It is established that high luminescence yield of the samples under study correlates with the content of anion vacancies and gamma-phase of Al2O3. The data for time-resolved luminescent spectroscopy are presented, which evidence for possible correlation between high TL and OSL activity and the F-type centers. It is noted that the material needs to be modified for successful use in dosimetry. In addition further studies to decrease the contribution of unstable (at 300 K) components to OSL and TL yields are required. (C) 2014 Elsevier Ltd. All rights reserved.
