| Abstract: | In this paper,the chelates, Eu~(3+)-M(Zn~(2+) ,Mg(2+),Ca(2+),Sr(2+),Ba(2+)Pyromellitic acid were prepared and their infared and Fluorescence spectra were also determined.The expermetnal result showed zine ions is the best in enhancing fluorescence of En(2+)-Pyromellitic acid.The effect of the doping concentration of zine ions on the fluorescence intensity of the chelate and fluorescenceEnhancement mechanism were also discussed.High efficiency red luminescent material EU(3+)-Zn(2+)-Pyromollitic acid,has beenSynthesized. |
