Abstract
The optically stimulated luminescence (OSL) of SrSO4:Eu (01mol%) powder samples was studied. The continuous wave OSL and linearly modulated OSL curves measured after irradiation by beta rays of 90Sr in the dose range of 0116—116kGy, illustrate that there are four components in OSL signal and the OSL dose response is linear-sublinear. Thermal stability of OSL signal was also measured, and the results showed that OSL from SrSO4:Eu is quite stable a t temperatures up to ～200℃. Meanwhile, the intensity of OSL signal is stronges t when the read temperature is about 180℃. The thermal luminescence(TL) three-d imensional spectra were measured after gamma rays irradiation (absorbed dose is 100Gy) of 60Co source. The emission wavelength at about 375nm indicate s that the luminescence comes from the transitions between energy levels of Eu 2+.
