Özet
Key characteristics of a newly prepared tissue-equivalent, highly sensitive thermoluminescence dosimeter, Li2B4O7: Cu, Ag, P, are presented. The material was developed at the Institute of Nuclear Sciences, Belgrade, in the form of sintered pellets. A new preparation procedure has greatly increased the sensitivity of the basic copper activated lithium borate and the glow curve of Li2B4O7 : Cu, Ag, P consists of a well-defined main dosimetric peak situated at about 460-465K with a sensitivity which is about four to five times higher than that of LiF : Mg, Ti (TLD-100). The exceptionally good response features of Li2B4O7 : Cu, Ag, P are attributed to the incorporation of Cu as a dopant. Both low and high temperature emission spectra are presented and the origins of the various emission bands are considered. Additional data are provided from electron paramagnetic resonance measurements.
