Kinetic parameters of some tissue equivalent thermoluminescence materials

Abstract

The paper reports a study on the kinetic parameters of some thermoluminescent tissue equivalent materials recently prepared in Vinca Institute: Li2B4O7:Mn,Si, Li2B4O7:Cu, Li2B4O7:Cu,In and MgB4O7:Dy,Na. The kinetics parameters have been determined using several methods. The temperature lag effect, which could produce large errors in the parameters' determination when they are determined using high heating rates, has also been taken into consideration.

Thermoluminescence characteristics of Li2B4O7:Cu,Ag,P

“…Kinetic parameters of the peaks obtained using the McKeever method are shown in Table 1. They are close to the results of Kitis' [12] . …”

Thermoluminescence of SrB4O7:Dy

“…In this paper, we report the TL properties of strontium tetraborate doped with dysprosium, an element widely used as activator in many other phosphors [1,[13][14][15][16][17][18]]. …”

Thermally stimulated luminescence glow curve structure of β‐irradiated CaB4O7:Dy

“…As seen from the figure, there are five noticeable plateaus, indicating that the 530 K peak is composed of five single peaks. Note that the PS method does not give accurate kinetic parameter values for materials with complex glow curves (22). To isolate the main glow peak of CaB 4 O 7 :Dy at 530 K from the low and high temperature peaks, the dosimeter was irradiated and heated to 438 K. After cooling to room temperature, the remaining glow curve was recorded.…”
