rates, peak shape and isothermal decay methods. Activation energy
results of this study are slightly higher than the results obtained in
the current study whilst frequency factors and kinetic order are
good agreement with the present research. The differences in the
activation energies may be due to different sample structure and
synthesis methods, which could have significant influence on defect
formation governing TL glow curve [32] .
4. Conclusion
In the present research work, kinetic parameters of newly
developed LBO:Mn single crystal has been carried out using initial
rise, isothermal decay and peak shape methods. This material is an
attractive because of its near tissue equivalency. It has two well
separated and simple glow peaks at 363 and 478 K with 1 K/s linear
heating rate. Moreover, there is no thermal quenching effect.
The main TL peak at 478 K of LBO:Mn single crystal obeys the general
order kinetics (b = 1.8). It means that there is some probability
of retrapping. All calculated kinetic parameters results were given
in Table 2.
The obtained results show that there is a good agreement between
the kinetic parameters calculated by three methods. This
indicates the reliability of three methods and accuracy of the measurement
of parameters.
