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.
A series of KAl(SO4)2 phosphors with different Eu3+ doping concentrations have been synthesized by solid-state reaction method. In the present work, the properties of synthesized Eu3+ doped KAl(SO4)2 phosphors have been examined by XRD, Photoluminescence (PL), and photometric characterization techniques. Under Near Ultraviolet (NUV) and blue excitation at 395nm and 466nm, PL emission spectra observed at 593nm and 614nm, which are ascribed due to 5D0→7F1 and 5D0→7F2 transition of Eu3+ ions. The emission band of 614 nm indicates the highest emission intensity compared to the 593 nm emission band. The PL emission spectra depict maximum intensity at 0.7mol% doping of Eu3+ ions. In addition, the synthesized Eu3+ activated KAl(SO4)2 phosphors show good color chromaticity coordinates, which is lies in the orange-red region. All these results indicated that the synthesized Eu3+ activated KAl(SO4)2 phosphors have potential results for future work in the field of solid state lighting.
