In the present study, the thermoluminescence (TL) properties of an Eu³⁺-doped CaNa₂(SO₄)₂ phosphor were studied. The Eu³⁺-doped CaNa₂(SO₄)₂ phosphor was synthesized using the combustion method. The samples were well crystallized in the monoclinic phase. The TL glow curve of the Eu³⁺-doped CaNa₂(SO₄)₂ phosphor showed a single prominent peak at around 210°C with showed linearity on increasing exposure. The response curve of the synthesized phosphor showed linearity in the range 500–7000 Gy. Trapping parameters of synthesized phosphors such as activation energy, frequency factor, and order of kinetics were calculated in the study. These trapping parameters were determined by different methods such as Chen’s peak method, the initial rise method, and Ilich’s method. Each characteristic of these outcomes demonstrated that the synthesized Eu³⁺-doped CaNa₂(SO₄)₂ phosphor had outstanding TL properties and might be valuable for TL dosimetry application.
