Abstract

Properties of thermally stimulated luminescence (TL) and optically stimulated luminescence (OSL) of the ceramic material A1N-Y2O3 have been studied after exposure to ultraviolet radiation (UVR). The dosemeter material Al2O3 : C has been used for comparative measurements. The spectral sensitivity ofthe samples has been studied and compared with spectral effectiveness of the UVR-induced biological processes, It has been shown that a very high yield and linear dose response characterise the UVR-induced TL from A1N-Y2O3. Although lower than the TL, the OSL signal from UV-exposed A1N-Y2O3 is still higher than that of Al2O3 : C in a broad spectral region. The possibilityof using A1N-Y2O3 ceramic for UVR dosimetry is discussed. (C) 2001 Elsevier Science Ltd. All rights reserved.
