摘要
The glow curve structure of CaSO4:Dy phosphor was studied in the dose range of (0.2-3.3)×105 Gy and it was found to be Dy-concentration-dependent in this range. The samples with high Dy-concentration (2.0 mol %) exhibit extended linearity and reduced supralinearity as compared to the normal concentration dosimetric samples (0.05 mol % Dy). In contrast to the results reported in literature, no difference in the TL fading was observed for these phosphors during a storage period of one month. © 1979.
