“…The peaks at 608, 744, and 830 cm À1 can be ascribed to vibrational modes of the R6G molecule for Ag [17]. with a slight red shift in the NBE, confirms the replacement of Y 3+ in the crystal lattice [8,28,29]. In this regard, this study provides valuable insights into understanding the role of defects in the optical properties of materials.…”

This work explores the thermoluminescence (TL) and photoluminescence (PL) properties of Ag/Y co‐doped zinc oxide (ZnO) nanophosphor. The proposed dosimeter was prepared by the coprecipitation method and sintered at temperatures from 400°C to 1000°C in an air atmosphere. Raman spectroscopy was studied to investigate the structural features of this composition. The new proposed dosimeter revealed two peaks at 150°C and 175°C with a small shoulder at high temperature (225°C). The PL spectrum showed strong green emissions between 500 to 550 nm. The Raman spectrum showed many bands related to the interaction between ZnO, silver (Ag), and yttrium oxide (Y2O3). The rising sintering temperature enhanced the TL glow curve intensity. The Ag/Y co‐doped ZnO nanophosphor showed an excellent linearity index within a dose from 1 to 4 Gy. The minimum detectable dose (MDD) of the Ag/Y co‐doped ZnO nanopowder (pellets) equaled 0.518 mGy. The main TL properties were achieved in this work as follows: thermal fading (37% after 45 days at 1 and 4 Gy), optical fading (53% after 1 h and 68% after 6 h by exposure to sunlight), effective atomic number (27.6), and energy response (flat behavior from 0.1 to 1.3 MeV). Finally, the proposed material shows promising results nominated to be used for radiation measurements.

“…Glasses preparation.-The synthesis of glass through the meltquenching technique as we reported in our previous works. 44,45 In this method there are a multi-step process that involves the transformation of raw materials into a homogeneous and amorphous glass structure. In our study, we synthesized a series of glasses with the chemical formula (75-x)B2O3- (10)TeO2-(13)SrCO3-(2)ZnO-(X)PbO, where the mole percentage (x) ranged from 0 to 40%.…”

Several radiation shielding parameters for (75-x)B2O3-10TeO2-13SrCO3 -2ZnO-xPbO glasses were evaluated between 0.284 and 1.333 MeV. The PbO content in the glass has a positive relationship with the density of the glasses, leading to BTSZP0, the glass with no PbO, having the smallest density, while BTSZP5, which has 40 PbO mol%, has the greatest density. Radiation shielding parameters such as mass attenuation coefficients and other related factors were computed, and relationships between PbO content, energy, and density are graphed. Linear attenuation coefficient (LAC) is reported and we evaluated the impact of density on the LAC values. By adding more PbO atoms, the density of the samples increased, leading to a higher LAC. The BTSZP0 sample has the highest HVL at all tested energies, with the BTSZP5 sample having the lowest HVL. Mean free path (MFP) has an inverse relationship with the density of each sample but increases with greater incoming photon energy. The effective atomic number (Zeff) values peak at low photon energies and rise significantly with increasing PbO content. The MFP and TVL of the BTSZP glasses are compared against previously tested glass samples at a set energy, and the values demosntrated the effectiveness of the BTSZP glasses.
