Özet

The kinetic parameters of a newly prepared tissue-equivalent, highly sensitive thermoluminescent detector, Li2B4O7: Cu, Ag, P of sintered pellets have been calculated. Thermoluminescence (TL) glow curves of Li2B4O7: Cu, Ag, P samples after beta-irradiation showed peaks at about 384 and 446 K with a heating rate of I K s(-1). The kinetic parameters, namely activation energy (E) and frequency factor (s) associated with the main glow peak (446 K) of Li2B4O7: Cu, Ag, P have been determined using isothermal decay (ID) and peak shape (PS) methods. The activation energies obtained by ID and PS methods are calculated to be 1.12 and 1.13eV (mean), respectively. The frequency factors obtained by both methods are 7.61 x 1011 and 3.53 x 1011 s(-1) (mean), respectively. Results obtained using both methods are compared and discussed. (c) 2007 Elsevier Ltd.
