TLDR
In this paper, the TL centres responsible for the formation of the peak at around 300°C in glow curves of sintered CaSO4-Dy dosimeters are formed during the sintering process and are probably located near grain boundaries in the Sintered material.About:

Differences in glow curves structure of nano- and microcrystals of CaSO4:Dy measured at a low heating rate
TL;DR: The glow curves of nano-and micro-crystals of CaSO4:Dy were measured at a low heating rate as discussed by the authors, and the glow peak maximum temperatures were almost the same for the nano- and microcrystals.

Multilevel based analysis of the thermoluminescence of CaSO4:RE (RE=Tm, Dy, Tb, and Sm)
TL;DR: In this paper, the multitrapping levels feature of thermoluminescent (TL) phosphors of CaSO4:RE (RE=Dy, Tb, and Sm) were analyzed using a variable heating rate method (including extremely slow heating rates of 0.001°C−1), the postannealing method, and the analysis of TL decay curves using x-ray induced luminescence (XIL) spectroscopy.

The thermoluminescence activation energy and frequency factor of the main glow of CaSO4:Tm phosphor determined by heating rate method including very slow rates of heating
TL;DR: In this article, the typical thermoluminescent phosphor of CaSO4:Tm was investigated using a heating rate method including very slow rates of heating, down to 00008°C−1 The analysis of the peak temperature values and the halfwidths of the resolved components in the glow curves by using various heating rates resulted in a distinctly higher activation energy (E) of 167-201 eV and a higher frequency factor (s) of 1019s−1 for resolved components.

The Electron Trap Mechanism of Luminescence in Sulphide and Silicate Phosphors
G F J Garlick,A F Gibson +1 more
TL;DR: Theoretical and experimental studies attempt to determine the extent to which retrapping does occur and what effects it will have in modifying the phosphorescence and thermoluminescence characteristics.

On the Calculation of Activation Energies and Frequency Factors from Glow Curves
TL;DR: In this article, a new method for calculating activation energies and frequency factors from thermoluminescence and thermally stimulated current peaks is described, which uses the total half width ω=T2−T1, where T1 and T2 are the half-intensity temperatures on the low and high-temperature side of the peak, respectively.

On the analysis of complex thermoluminescence. Glow-curves: Resolution into individual peaks
TL;DR: In this paper, a method for estimating the number and position of individual thermoluminescence (TL) peaks within a complex glow-curve is described, which involves partially heating the sample to a temperature TStop cooling to room temperature and re-heating to record all of the remaining glowcurve.

Methods for kinetic analysis of thermally stimulated processes
TL;DR: Several methods are known for the evaluation of the main kinetic parameters related to a thermoluminescence (TL) curve, namely the activation energy, the preexponential factor and the kinetic order as discussed by the authors.
