“…In fact, radiation‐induced luminescence phenomena related to the Cu + in Cu‐doped glasses have been widely investigated. However, many of these studies have focused on the thermoluminescence, optically stimulated luminescence, lyo—and mechano‐luminescence phenomena, or scintillation properties . Investigations of the RPL phenomena of Cu are very limited .…”

Radiophotoluminescence phenomena have been widely investigated on various types of materials for dosimetry applications. We report that an aluminoborosilicate glass containing 0.005 mol% copper exhibits intense photoluminescence in the visible region induced by X‐ray and γ‐ray irradiation. The luminescence is assigned to the 3d94s1 → 3d10 transition of Cu+. The proportionality of the intensity of the induced photoluminescence to the irradiation dose was confirmed up to 0.5 kGy using 60Co γ‐ray irradiation. Based on the spectroscopic results, a potential mechanism was proposed for the enhancement of the photoluminescence. The exposure to the ionizing radiation generates electron‐hole pairs in the glass, and the electrons are subsequently captured by the Cu2+ ions, which are converted to Cu+ and emit the luminescence. For the glass containing 0.01 mol% copper, the pronounced enhancement of the photoluminescence was not observed because the reverse reaction, ie, the capture of the holes by the Cu+ ions, becomes prominent. The photoluminescence induced by the irradiation was stably observed for the glasses kept at room temperature and even for the glasses heat‐treated at 150°C. However, the induced photoluminescence could be eliminated by the heat treatment at a temperature at 500°C, and the glass returned to the initial pre‐irradiation state. The Cu‐doped aluminoborosilicate glass is a potential candidate for use in dosimetry applications.

The thermoluminescence technique was employed to study bioglass matrices prepared using the traditional technique of glass making. The synthesized bioglass matrices were investigated using X-ray diffraction (XRD), and differential thermal analysis (DTA) has been studied. The highest thermoluminescent intensity was found for the bioglass matric of 26.91% CaO, 46.134% SiO 2 , 2.60% P 2 O 5 , 24.34%Na 2 O (mol%), with only one glow peak at 460 k. The TL response illustrations linearity in high gamma dose range from 25 to 1000 Gy. This new bioglass matric might become useful in high-dose elds for dosimetry.
