Thermoluminescence dosimetry properties of calcium and dysprosium activated zinc gallate nanocrystals

Mansoureh Tatari et al.

Summary: ZnGa2O4:Ca and ZnGa2O4:Dy nanocrystals were synthesized using the sol-gel method and their thermoluminescence and dosimetric characteristics were studied. The main TL glow peaks of ZnGa2O4:Ca and ZnGa2O4:Dy were observed at approximately 180 degrees C and 200 degrees C, respectively. The optimal concentration for both dopants was found to be around 2 mol%, with ZnGa2O4:Dy nanoparticles exhibiting 1.5 times higher sensitivity than ZnGa2O4:Ca samples. Additionally, the dosimetric peak showed good linearity up to 5 kGy in both activated nanocrystals. The presented nanophosphors show promise for dosimetric applications.

Thermoluminescence characteristics and kinetic analyses of europium doped strontium gadolinium oxide phosphor

S. Sarikci et al.

Summary: SrGd2O4 phosphors doped with different concentrations of Eu3+ were synthesized using the solid state reaction method, and their structural and thermoluminescent properties were examined using X-ray diffraction (XRD) and thermoluminescence (TL) techniques. XRD confirmed the orthorhombic phase formation of Eu3+ doped samples. The influence of impurity concentration and heating rates on the glow curves was investigated, and an anomalous heating rate pattern was observed in the sample with Eu3+ additive. The TL glow curves of beta irradiated SrGd2O4:Eu3+ (0.25 mass %) exhibited three well-resolved peaks at 105, 189, and 245 degrees C.

Characterization, room and low temperature photoluminescence of yttrium aluminium borate activated with Sm3+ions

A. Y. Madkhli et al.

Summary: The combustion method assisted by urea was used to synthesize reddish orange emitting YAl3(BO3)4 phosphor samples doped with various Sm3+ concentrations. The structural and luminescence properties of the synthesized samples were studied in detail. XRD analysis showed a rhombohedral structure with an R32 space group (155), and the particle size was determined to be 48 nm. Visible PL emission spectra under 359 nm excitation exhibited four peaks at 564 nm, 599 nm, 646 nm, and 707 nm, corresponding to transitions 4G5/2 -> 6H5/2, 4G5/2 -> 6H7/2, 4G5/2 -> 6H9/2, and 4G5/2 -> 6H11/2. Concentration quenching was caused by dipole-dipole interactions between neighboring Sm3+ ions. The optimized sample (x = 0.03) showed admirable luminous performance with CIE chroma coordinates (0.606, 0.382). YAl3(BO3)4:Sm3+ can be a good candidate for red component in lighting applications.

Anomalous heating rate dependence and analyses of thermoluminescence glow curves in Gd doped ZnB2O4 phosphors

S. Atasoz et al.

Summary: In this study, the TL characteristics and trapping parameters of pelletized Gd-incorporated ZnB2O4 synthesized through the gel combustion method were investigated. The XRD results confirmed the chemical composition of the obtained Gd-incorporated ZnB2O4. It was found that the optimal doping concentration of Gd was 0.25 mass%, which resulted in the highest luminous efficiency. The glow curves of the pellet-formed samples exposed to beta-irradiation showed distinct peaks at specific temperatures. The TL glow peaks were studied using various methods, revealing complex glow curves composed of six distinguishable peaks. The results suggest that ZnB2O4:Gd3+ phosphor is a suitable option for radiation dosimetry in environmental monitoring.
