Afterglow in synthetic bazirite, BaZrSi_3O_9 TAKAHASHI Yoshihiro MASAI Hirokazu FUJIWARA Takumi KITAMURA Kenji INOUE Satoru 社団法人日本セラミックス協会 日本セラミックス協会学術論文誌 : Nippon Seramikkusu Kyokai gakujutsu ronbunshi = Journal of the Ceramic Society of Japan 18820743 116 1350 357 360 2008-02-01 A blue afterglow was observed in the bazirite-type BaZrSi_3O_9 synthesized by a solid-state reaction for the first time. The synthetic bazirite phase showed a clear blue long-lasting luminescence at room temperature after the exposure of UV light, in spite of the free from any lanthanide-doping. It was proposed that the afterglow in the BaZrSi_3O_9 phase was originated from the occupation of Ti^<4+> as an impurity in the distorted octahedral site. 2008-02-01 110006571108 AA12229489 9352053 ENG CJP NDL NII-ELS J-STAGE 3 17 Afterglow in synthetic bazirite, BaZrSi_3O_9 TAKAHASHI Yoshihiro MASAI Hirokazu FUJIWARA Takumi KITAMURA Kenji INOUE Satoru The Ceramic Society of Japan Journal of the Ceramic Society of Japan A blue afterglow was observed in the bazirite-type BaZrSi_3O_9 synthesized by a solid-state reaction for the first time.
