dc.description.abstractPotassium aluminum phosphate (KAP) glasses in the system xKPO(3)-(100-x)AI(PO3)3 with x = 10, 30 and 50 mol% were prepared in the metaphosphate composition. The glasses were doped with MnO2 and their thermoluminescent (TL) response was investigated. Raman spectra showed that these glasses did not undergo structural changes with the substitution of manganese ions. The glass composition x = 50 mol% doped with 1.0 mol% of MnO2 presented the best TL response. The material displayed good sensitivity for gamma-rays, X-rays and UV light. The emission curves exhibited two TL peaks, one at a low temperature (similar to 150 degrees C) and the other at a high temperature (similar to 365 degrees C), whose positions were dependent on the type of exciting radiation applied. The results of the present study indicated that the high temperature peak is a good candidate for TL dosimetric investigations. (c) 2006 Elsevier B.V. All rights reserved.en
