Physiochemical, Radiative Transitions and Thermoluminescence Characterizations of Nano Ce-Doped Bati5o11

Abstract

This article reports the preparation, analytical, and thermoluminescence (TL) characterization of BaTi5O11 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 sample 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. The study confirms the good TL dosimetric properties and, therefore, the potential of using 0.7% Ce-doped BaTi5O11 sample for beta dosimetric applications.
