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 amounts of Ce. The Sol–gel technique was used to synthesize the doped nanocrystals. The prepared samples were examined by XRD, EDX, UV–Vis spectrophotometry, SEM, and TEM techniques to determine their analytical features. The samples with 0.7% Ce doping showed the best thermoluminescent behavior among the samples we made. The glow curves analysis showed that there were seven peaks that overlapped with each other. The thermal activation energy values of the carrier traps are 0.93, 1.08, 1.16, 1.23, 1.29, 1.35, and 1.38 eV. This study displayed that 0.7% Ce-doped BaTi ₅ O ₁₁ can be used in monitoring high doses radiation applications.
