Physiochemical, radiative transitions and thermoluminescence characterizations of nano Ce-doped monoclinic barium titanate

This article reports the preparation, analytical, and thermoluminescence (TL) characterization of BaTi ₅ O ₁₁ doped with different concentrations of Ce. The Sol-gel technique was used to synthesize the doped nanocrystals. The prepared samples were examined by XRD, EDX, UV-V _is spectrophotometry, SEM, and TEM techniques to determine their analytical features. The samples with 0.7% Ce doping showed the highest TL sensitivity for ionizing radiation among the samples prepared with different concentrations. The glow curves analysis showed that there were seven peaks that overlapped with each other with thermal activation energies: 0.93, 1.08, 1.16, 1.23, 1.29, 1.35, and 1.38 eV. The dose-response linearity and reusability measurements displayed that 0.7% Ce-doped BaTi ₅ O ₁₁ can be used in monitoring high doses radiation applications.
