Abstract

The Eu-L3 edge XANES and luminescent spectra of CaBPO5:Eu

SrB4O7:Eu and Ba3（PO4）2:Eu prepared by solid state reaction at high temperature in air were determined. It can be observed from the Eu-L3 edge XANES spectra that energy of Eu3+-L3 edge is 7-8 eV higher than that of Eu2+-L3 edge in the luminescent materials. The 4f-5d transition of Eu2+ and the 4f-4f transition of Eu3+ can be found simultaneously in the excitation and emission spectra of these materials

respectively. The results of Eu-L3 edge XANES and luminescent spectra imply that Eu3+ can be partially reduced to Eu2+ in these materials when they were prepared in air atmosphere.
