“…Afterglow or storage phosphor is an inorganic compound that traps free electrons and holes in compound lattice defects after exposure to ionizing radiation or high energy photons such as 254 nm UV-light. [1][2][3][4][5] The stored charge carriers can later be excited to yield rapid photon emission by thermal, 6,7 optical, 8,9 or mechanical stimulation. [10][11][12] Because of this feature, storage phosphors have many promising applications in X-ray computed tomography (CT), 13 dosimeters for radiation detection, [14][15][16] information storage, 17,18 anti-counterfeiting, 19 and even exploring mechanoluminescence materials for smart compression force sensing.…”

A Versatile Photochromic Dosimeter Enabling Detection of X‐Ray, Ultraviolet, and Visible Photons

An accurate measurement of radiation doses is required to ensure efficient use of electromagnetic radiation in medical diagnostics, agriculture, or general lighting applications. Yet, existing dosimeters usually face the issues of cumbersome manipulation, time-consuming analysis, or power-supply requirement. Here, an all-round dosimeter is reported based on BaMgSiO 4 , a photochromic material that exhibits a reversible white-pink color change upon irradiation. Electron paramagnetic resonance measurements under in situ coloring and bleaching reveal that the charge carrier trapping and detrapping at oxygen vacancy-related defects determine the photochromic behavior. This can be utilized for dosimetry of X-rays, ultraviolet, and visible light, as the coloring and bleaching are dependent on the irradiation wavelength and the dose. The distinct color variation of BaMgSiO 4 allows for on-site measurement of irradiation doses by a colorimetric method, and the special wavelength-responsive behavior in the ultraviolet region is suitable for personal solar ultraviolet light monitoring. By virtue of good stability and excellent cycling robustness, BaMgSiO 4 can be an ideal integrating detector for X-rays, ultraviolet, and visible light dosimetry. A prototype device is also developed for long-duration daylight measurements. These findings enhance the understanding of the photochromic behavior in inorganic materials and can stimulate the exploration of new photochromic dosimeters.

“…TLD remains the most powerful method to measure radiation doses due to its reliability, non-intricacy, and portability [1,3,[9][10][11]. The thermoluminescence (TL) mechanism depends on impurities defects in the crystal structure, which increment the capacity of the materials to store radiation energy [6,[11][12][13].…”

Development of Ag-Doped ZnO Thin Films and Thermoluminescence (TLD) Characteristics for Radiation Technology

This work examined the thermoluminescence dosimetry characteristics of Ag-doped ZnO thin films. The hydrothermal method was employed to synthesize Ag-doped ZnO thin films with variant molarity of Ag (0, 0.5, 1.0, 3.0, and 5.0 mol%). The structure, morphology, and optical characteristics were investigated using X-ray diffraction (XRD), scanning electron microscope (SEM), energy-dispersive X-ray spectroscopy (EDX), photoluminescence (PL), and UV–vis spectrophotometers. The thermoluminescence characteristics were examined by exposing the samples to X-ray radiation. It was obtained that the highest TL intensity for Ag-doped ZnO thin films appeared to correspond to 0.5 mol% of Ag, when the films were exposed to X-ray radiation. The results further showed that the glow curve has a single peak at 240–325 °C, with its maximum at 270 °C, which corresponded to the heating rate of 5 °C/s. The results of the annealing procedures showed the best TL response was found at 400 °C and 30 min. The dose–response revealed a good linear up to 4 Gy. The proposed sensitivity was 1.8 times higher than the TLD 100 chips. The thermal fading was recorded at 8% for 1 Gy and 20% for 4 Gy in the first hour. After 45 days of irradiation, the signal loss was recorded at 32% and 40% for the cases of 1 Gy and 4 Gy, respectively. The obtained optical fading results confirmed that all samples’ stored signals were affected by the exposure to sunlight, which decreased up to 70% after 6 h. This new dosimeter exhibits good properties for radiation measurement, given its overgrowth (in terms of the glow curve) within 30 s (similar to the TLD 100 case), simple annealing procedure, and high sensitivity (two times that of the TLD 100).
