This study investigates the structural, microstructural, and thermoluminescence (TL) properties of a Leucite-Coesite ceramic coating designed for metal-based dental applications. A comprehensive characterization was performed using X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), and TL analysis to assess crystallinity, phase composition, and luminescence behavior. Energy-dispersive X-ray spectroscopy (EDX) confirmed the presence of key elements, while FTIR revealed characteristic Si–O and Al–O vibrational modes, indicating a stable aluminosilicate structure. TL analysis revealed a dose-dependent response with distinct glow peaks, suggesting potential applications in radiation dosimetry. The TL intensity exhibited a moderate increase with heating rate (∼10 %), deviating from classical first-order kinetics. This behavior may reflect non-classical recombination mechanisms involving spatial correlations between traps and recombination centers. Glow Curve Deconvolution (GCD) analysis identified nine distinct TL peaks with activation energy values ranging from 0.80 eV to 1.42 eV. These results indicate the presence of well-separated kinetic components with consistent parameter estimates. These findings highlight the complex charge carrier dynamics in Leucite-Coesite ceramics and underscore their potential for both restorative dentistry and radiation dosimetry.</div></div>","PeriodicalId":20861,"journal":{"name":"Radiation Physics and Chemistry","volume":"237 ","pages":"Article 113037"},"PeriodicalIF":2.8,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144221724","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to evaluate and compare the S-values of radionuclides that have been investigated for HCC radionuclide therapy including 131I, 90Y, 188Re, 166Ho, 125I, and 67Cu. Using the InterDosi code version 1.3 in conjunction with the Digimouse voxelized phantom, we calculated S-values for two HCC radionuclide therapy scenarios representing the early and terminal stages of the disease by considering a small tumor in the liver and the whole liver as separate radiation sources. The results highlight significant variations in dose distribution, which affect both therapeutic efficacy and the protection of healthy tissues. Indeed, in the first scenario while the small tumor in the liver is irradiated, both 67Cu and 131I exhibited high S-values, with variations between them of less than 10 %. Notably, 67Cu enabled a substantial reduction in dose absorption in neighboring organs, reducing exposure by 54 %–71 % compared with 131I, making it a safer option for treatment. Whereas, in the second scenario in which the whole liver is irradiated, 90Y and 188Re had the highest S-values, delivering homogeneous doses throughout the liver, but also resulting in higher exposure of surrounding organs. In contrast, 67Cu showed moderate S-values while significantly reducing doses to non-target organs, with kidney exposure reduced by 97.9 % compared to 90Y.
