Thermoluminescent properties of Sr2P2O7 doped with copper and some rare earth elements

In this study. Sr2P2O7 was doped with some rare earth oxides (Pr6O11, Nd2O3, Dy2O3, Ho2O3, Er2O3, and Tm2O3) at 0.5%, 1%, 2%, 3%, 4%, 5%, 10%, and 15% (by weight) and co-doped with CuO by heating at 900 C for 10 h. Structural analysis of the products was carried out by powder X-ray diffraction (XRD). XRD patterns of the samples showed that doping did not alter the orthorhombic structure of the Sr2P2O7. Thermoluminescence (TL) glow curve measurements were obtained and these showed that Pr and Cu-doped Sr2P2O7 exhibit very significant thermoluminescence glow peaks, suggesting these could be promising dosimetric materials. Bearing this in mind, some TL dosimetric properties of Sr2P2O7:Cu,Pr compounds are presented in this paper, confirming they are promising for this application. (C) 2010 Elsevier B.V.
