| Abstract: | 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. |
