Leucite: and Coesite-based ceramic materials have garnered significant attention for their potential use in dental restorations due to their enhanced mechanical strength, thermal stability, and aesthetic properties. 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.
