| 摘 要： | 本文报道合成了可发出粉红色荧光的含铽络合物２－萘甲酸－邻菲罗啉－铽，并对其进行了荧光光谱及红外光谱研究，结果表明，由于２－萘甲酸，邻菲罗啉配体的混配作用，使铽离子的＾５Ｄ４－＾７Ｆ３跃迁产生较强的６１５ｎｍ发射峰，其发射强度大于由＾５Ｄ４－＾７Ｆ５跃迁产生的５４５ｎｍ发射峰，因而络合行发出粉红色荧光。

| Abstract: | Usually, the emission spectra of terbium complexes exhibit 490 nm, 545 nm bands (green color) under the excitation of UV light, which is ascribed to the two 5D4 - 7F6, 5D4 - 7F5 transition. In this report, pink red fluorescence under the excitation of 300-370nm UV light is observed for a new 1, 10-phenanthroline-2-naphthoate complex of terbium. The fluorescence, FT-IR, ICP and X-ray fluorescence analysis were performed. The results showed that under the perturbation of the ligands field, the probability of 5D4 - 7F3 transition of terbium ion was greatly enhanced, while the probability of 5D4 - 7F5 transition was greatly decreased in the complex. Therefore, pink-red fluorescence was observed for the title complex. |
