During our entire study we have utilized the property of Eu(III) ion for luminescence as well as cyclic voltammetry study. The Eu(III) ion is utilized as model system for both the techniques because it provides very good emission spectra looking to the electron configuration of Eu(III) ion, Eu(III) ion is the one of the few lanthanide, which exited its divalent state and this divalent state found very stable because of 4f7 configuration.
