| Abstract(in English) | 癌診断の方法の一つとして蛍光生体イメージングが期待されている．これまでの研究で液相反応法を用いてCa10(PO4)6(OH)2：Mn5+ (HAp：Mn5+) ナノ粒子蛍光体の作製に成功している．しかし，発光強度が非常に弱いため， CaサイトをBaに変えたBa10(PO4)6(OH)2：Mn5+ (BaHAp：Mn5+) を作製したところ，従来のHAp:Mn5+に比べ数十倍~100倍に発光を向上できた．しかし，Baは生体に対して毒性があるため，毒性を抑えつつ発光改善のためにMn5+の付活量を増やす事や新たな母体材料Ca6BaP4O17 (CBPO) に着目した．CBPOのBa濃度を22~28%の範囲で2%刻みとして作製し発光特性の評価を行った．全ての試料において不純物相が生成されていたが，Ba濃度が低くなるにつれ不純物相のピークが弱くなり，それに伴い発光強度が増加した．本研究で作製した試料のうちBa22%が最も発光する結果となった．XRDとPLスペクトルには相関性があると考えられ，更にBa濃度を減らすことで発光強度を改善出来ると考えている． |
