Thermoluminescence properties of NaSrBO₃:Eu phosphor for gamma, carbon, and oxygen ion beam irradiation

Thermoluminescence (TL) properties of Eu-doped NaSrBO₃ phosphor under gamma (γ), Carbon-ion beam, and Oxygen ion beam -irradiation were studied. The phosphor was synthesized by using solid-state method with different concentrations of Eu (0.05, 0.2, 0.5, 0.7, 1.0 mol%). We studied TL glow curve of proposed material with different concentration of Eu ions and different exposer of radiations. The TL glow curves were studied for the gamma dose range from 0.12 to 1.2 KGy. The glow curves show the maximum TL intensity for 0.1 mol% concentration of Eu. In addition, proposed material was investigated under Carbon-ion beam and Oxygen ion beam -irradiation. Trapping parameters were determined using Chen’s peak shape method, the Initial Rise (IR) method, and Ilich’s method. The glow curves were further analyzed to assess the dosimetric properties, including dose response, fading, and concentration quenching. The dose–response was found to be nearly linear across the measured range, indicating the potential of these phosphors for dosimetry applications.
