【摘要】 合成了均苯四甲酸（ＰＭＡ）与铽离子和常见二价金属离子（Ｃａ(２＋)、Ｓｒ(２＋)、Ｂａ(２＋)、Ｍｇ(２＋)、Ｚｎ(２＋)、Ｍｎ(２＋)、Ｃｄ(２＋)、Ｃｕ(２＋)）形成的系列配合物，发现了钙对均苯四甲酸铽荧光的强增敏作用。常温下研究了它们的荧光光谱，找到了Ｔｂ(３＋)离子在配合物ＣａＰ－ＭＡ：Ｔｂ中发光的最佳浓度，探讨了有关荧光增敏机理，得到了Ｃａ(２＋)的摩尔分数为４／５（即Ｃａ(２＋)／Ｔｂ(３＋)＝４：１）的鲜艳绿色发光材料ＣａＰＭＡ：Ｔｂ。更多还原

【Abstract】 In this paper, the chelates, pyromellitic acid-terbium-common divalent canon such as calcium ions were was prepared by pyromellitic acid with Tb chlorides and Ca chlorides. The experimental result showed calcium ions is best in common divalent canon in enhancing fluorescence of pyromellitic-terbium. The fluorescence spectra of pyromellitic acidterbium-calcium was determined at room temperature;fluorescene enhancement mechanism is also put forwarcl. High efficiency green luminescent materials,terbium-pyromellitic acid- Calcium (Tb3+: Ca2+ =1: 4) has been synthesized.更多还原
