Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms
الملخص العربي
The three points analysis method was applied to determine the number of peaks and kinetic parameters. These are the order of kinetics
b, the activation energy E (eV), the frequency factor S (s1
) or the pre-exponential factor S00 (s1
) and the relative value of the initial
concentration of trapped electrons n0 (cm3
) associated with the thermoluminescence (TL) glow peaks in double potassium yttrium fluoride
(K2YF5) doped with cerium ions (Ce3+) in response to b-irradiation. The three points analysis method indicated that the glow curve
of this material is the superposition of five general-order components, which was referred to as P1–P5, in the temperature range between
room temperature and 500 C.
