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.

“…These results are observed in tissue and nontissue equivalent nanomaterials [13][14][15][16][17][18][19][20][21]. Other workers have also participated in testing TL response of some nanostructure materials to different ionizing radiations [22][23][24][25][26][27][28]. These studies showed that the TL response of these nanomaterials to ionizing radiations is mostly linear in a wide range of exposures; however, few studies were focused on the TL response of low effective nanomaterials.…”

Nanostructures of calcium fluoride (CaF2) doped with Eu, Tb, Dy, Cu, and Ag were synthesized by the coprecipitation method and studied for their thermoluminescence (TL) and photoluminescence (PL) properties. The PL emission spectrum of pure CaF2nanostructure has a broad band in the 370–550 nm range. Similar spectra were observed in case of doped samples, beside extra bands related to these impurities. The maximum PL intensity was observed in Eu doped sample. The TL results of Eu, Cu, Ag, and Tb doped samples show weak glow peaks below 125°C, whereas Dy doped one is found to be highly sensitive with a prominent peak at 165°C. This sample was further exposed to a wide range of gamma rays exposures from137Cs source. The response curve is linear in the 100 Gy-10 kGy range. It is also observed that the particle size of CaF2nanostructure was significantly reduced by increasing Dy concentration. These results showed that Dy is a proper activator in the host of CaF2nanostructure, providing a highly sensitive dosimeter in a wide range of exposures and also plays a role as a controlling agent for particle size growth.

“…The TL reaction, similar to all the energies of ionizing radiation, is seen as having a high linearity of the TL signal with respect to the light, and the high efficiency of the lower limit region, the less dim, and radiation region. Also part of the late lanthanide arrangement is unusual earth-sized base earth sulfate phosphors, and for example CaSO4: Dy and CaSO4: Tm has high TL impact and insignificant shadow applied to environmental and temporal dosimetry [25].…”

Rarely measured barium calcium sulfate (Ba1-xCaxSO4: Dy 3+ , Er 3+) phosphor material in the research and interpretation of lanthanide series. The solution is obtained from the combustion process. The structure of the objects was confirmed bay X-ray analysis. Also to be consistent with the intensity of the refinement scheme to study the benefits of the fit values, its morphological personality was scanned by scanning with electronic microscopy (SEM). Mixed alkaline rare earth substance Ba1-xCaxSO4: Dy 3+ , Er 3+ are used for the study for Photoluminescence and thermoluminescence. Here I summarize the thermoluminescence properties of dysprosium and erbium the low, high dose response. The frequency factor (s) and activation energy (E) both were calculated by the first and second law, Chen's half-width method.
