The only recipient for the electrons are Eu3+ ions. It is therefore reduced into Eu2+ by the electrons.

As the amount of aluminium powder with reducing activity that was incorporated increases, a portion of Eu3+ was reduced to Eu2+, it is reflected by the fact that the Eu2+ emission was increased and Eu3+ emission was decreased, which is also in consistent with the xps results. We can clearly show that both types of Eu ions with different valencies were changed proportionally to the increased amount of aluminium powder with reducing activity that was incorporated, which is accompanied with the changes in intensity from corresponding Eu ions.
