Abstract(in English) | The effect of plasma treatment on the luminance efficacy of BaMgAl_<10>O_<17>:Eu^<2+> (BAM:Eu^<2+>) is investigated. Among argon-based plasmas with hydrogen or oxygen, it is confirmed that the hydrogen addition to argon plasma supremely improves the lifetime of BAM:Eu^<2+>. The photoluminescence (PL) and thermoluminescence (TL) measurements reveal that the electron traps closely concerned with degradation are reduced by the hydrogen plasma. The PL measurements on BaMgAl_<10>O_<17> strongly suggest that the vacancies and/or defects in BAM crystal are somehow repaired by hydrogen bridge formation. |
