概要
- 論文の詳細を見る
Thermoluminescence of Eu and Ce co-doped CaGa_2S_4 has been investigated for the first time. All co-doped samples were found to exhibit a long afterglow of the Eu emission having a peak energy of 〜2.20eV. Analyses of measured transient thermoluminescence curves showed two activation energies. 〜0.2eV and 〜0.94eV, for most co-doped samples. These two activation energies are shown to be explainable by the model which includes one trap level with two activation processes, and hole release from the terminal state of the Eu ion. Experimentally observed thermoluminescence curves are shown to be well reproduced by the theoretically formulated model which takes into account the above-mentioned hole release process.
