摘要
合成了ＰＭＡ－Ｔｂ３＋、ＰＭＡ－ＴＰＰＯ（Ｐｈｅｎ）－Ｔｂ３＋及其掺杂Ｙ３＋、Ｇｄ３＋的系列配合物，常温下研究了它们的固体粉末荧光光谱，发现在二元配合物中掺杂Ｙ３＋比掺杂Ｇｄ３＋发光强，在三元配合物中以三苯基氧化膦作第二配体比以邻菲罗林作第二配体的配合物发光强，得到了鲜艳绿色的高效荧光材料ＰＭＡ－ＴＰＰＯ－Ｔｂ３＋－Ｙ３＋。
In this paper,the chelate,pyromellitic acid Tb 3+ TPPO was prepared by pyromellitic acid with TPPO and Tb chlorides in ethanol solution,the influence of Gd 3+ and Y 3+ on the fluorescence of the chelate was also studied.The fluorescence spectra of solid phosphor were determined at ambient temperature.The experimental result showed that Y 3+ ions are better than Gd 3+ ions in enhancing fluoresence of the chelate and the luminescence of pyromellitic acid Tb 3+ TPPO is stronger than that of pyromellitic acid Tb 3+ Phen.High efficiency sharp green luminescent materials,pyromellitic acid TPPO Tb 3+ Y 3+ (Tb 3+ /Y 3+ =0.25)have been synthesized.
