摘　　要：观察了以不同比例溶解在乙醇中的ＥＵ（３＋）、Ｔｂ（３＋）、１－乙酰乙酰吲哚（ＨＬ）和１，１０－邻菲啉（Ｐｈｅｎ）的荧光光谱．结果表明ＨＬ能有效地把吸收的能量传递给Ｔｂ（３＋），而不能有效地传递给Ｅｕ（３＋）．讨论了ＨＬ和Ｐｈｅｎ对Ｅｕ（３＋）、Ｔｂ（３＋）的配位作用及其对Ｅｕ（３＋）或Ｔｂ（３＋）所组成的三元体系中敏化发光性能的影响．The fluorescence of Eu3+ and Tb3+ ions complexed with l-acetylacetoindole (HL) and l, 10-phenanthroline(Phen) in ethanol solution was investigated. It was found that there is a different influence for the addition of HL into the Eu3+-Phen and Tb3+-Phen systems respectively. This difference is discussed according to the ability of sensitization of HL for the luminescence of Eu3+ and Tb3+ respectively and also the coordination property of HL and Phen with Eu3+ and Tb3+.
