The morphological, structural, and thermoluminescence (TL) properties of LiF:SiO5 doped with Ce3+ solid powder phosphor were systematically analyzed. X-ray diffraction (XRD) confirmed the crystalline nature single-phase LiF:SiO5:Ce3+ nanoparticles (NPs), size (D) determined using Williamson–Hall (W–H) Scherrer methods. doping induced structural modifications, reflected in variations full width at half maximum (FWHM), strain, stress values. TL glow curve revealed two distinct peaks approximately 64 °C 134 °C, shedding light on electron capture release mechanisms following beta irradiation. A dose-dependent study demonstrated that intensity increased proportionally radiation exposure, showing a superlinearity relationship up to 6 Gy. Additionally, investigations into different heating rates indicated only slight shift peak temperature, confirming thermal stability materials. This provides valuable insights behavior LiF:SiO5:Ce3+, making it promising candidate for dosimetry luminescence applications.
