Abstract
In this paper, thermoluminescence (TL) properties such as glow curves analysis, dose response linearity and some dosimetric characteristics of pure and carbon doped lanthanum aluminate (LaAlO3) produced by different syntheses using the solid state reaction method are investigated, after exposure to different UV radiation doses. The effect of different syntheses on the TL glow curves structures is also investigated and discussed. TL glow-curve deconvolution (CGD) methods and the Chen's peak shape methods were used to analyze the sets of TL glow curves. The kinetic parameters of TL single peaks were computed. Additionally, the life times (Ï) of electrons in trap for all samples were determined and calculated. A good linear dose response over the dose range from 0.21 to 1.26Â mJ/cm2 has been attributed to both samples (B and C).
