Abstract: The synthesis of AEu2I5(A=K, Rb, Cs) by a one-step method has been reported. The crystal structure of these compounds were determined by X-ray powder diffraction. The europiumvalence, which was determined from polarography and UV-absorbance spectrum,is 2+. Thecomposition, lattice parameters, melting point, density, polarogrphy voltage. UV-absorbancespectrum and fluorescence spectra of A Eu2I5 have been presented. |
Keywords: KEu2I5 RbEu2I5 CsEu2I5 di-valence rare earth compound |
