“…Recently, many research groups worldwide have been involved in exploring the best TLD for radiation dosimetry. Numan Salah and colleagues studied the thermoluminescence properties of Al 2 O 3 :Tb nanoparticles and LiF:Eu exposed to γ‐rays and 85 MeV C 6+ ion beams. Gieszczyk and colleagues studied thermoluminescence and optically stimulated luminescence of LiMgPO 4 synthesized using a micropull‐down technique .…”

Thermoluminescence (TL) materials exhibit a wide range of applications in different areas such as personal dosimetry, environmental dosimetry, medical research etc.Doping of different rare earth impurities in different hosts is responsible for changing the properties of materials useful for various applications in different fields. These materials can be irradiated by different types of beams such as γ-rays, X-rays, electrons, neutrons etc. Various radiation regimes, as well as their dose-response range, play an important role in thermoluminescence dosimetry. Several TL materials, such as glass, microcrystalline, nanostructured inorganic materials and recently developed materials, are reviewed and described in this article.

“…A wide linear TL response has been observed for nanocrystalline β-Ca 2 P 2 O 7 :Dy material while other microcrystalline materials shows early saturation towards ion beam irradiation. The reason behind wide TL response of nanocrystalline phosphor is already explained by several authors in the earlier work 4,5 . A shifting of position of maximum glow peak temperature is observed (Fig.…”

Dy3+ doped β-Ca2P2O7 phosphor has been synthesized using wet chemical method. The scanning electron microscopy (SEM) and transmission electron microscopy (TEM) analysis confirmed the formation of β-Ca2P2O7:Dy nano-phosphors. However, photoluminescence (PL) study was carried out to confirm the presence of dopant ion in the host matrix of β-Ca2P2O7:Dy material. Thermoluminescence (TL) glow curves of β-Ca2P2O7 were recorded for different concentrations of Dy3+ after exposure to various fluences of C6+ ion beam (75 meV). TL sensitivity of β-Ca2P2O7:Dy3+ (0.1 mol%) phosphor was 3.79 times more than commercially available CaSO4:Dy3+. TRIM code based on the Monte Carlo simulation was used to calculate the absorbed doses, ion range and main energy loss. Glow curve de-convolution (GCD) method was used to determine the number of TL peaks and their trapping parameters. The wide linear response of β-Ca2P2O7 nanoparticles along with high stability of TL glow curve makes this nanomaterial a good candidate for C6+ ion beam dosimetry.

Abstract. In this work, Al2O3 doped with Sr, Li and Ge was prepared by combustion synthesis techniques for thermoluminescent (TL) ionizing radiation dosimetry applications. Dopants sample concentration were varied from 0.1 mol% to 5 mol% in order to study the effect of the concentration on the TL response. The optimum concentration was found to be 0.3 mol% for Sr and Li and 3.0 mol% for Ge. Based from the comparison of this doped material, the highest sensitivity was found for Ge doped and linear response for doses studied range of 10-80 Gy. X-Ray diffraction (XRD) patterns of the samples were recorded to confirm the formation of the sample. The sharp peaks present in the XRD confirms the sample is crystalline. The TL response of these samples for Co -60 gamma radiation were evaluated. It was observed a TL glow peak around 175°C for doped sample which is suitable for radiation dosimetry.
