摘要：
In SrO · 6Al2O3 : Eu2+ phosphor, blue Eu2+ luminescence is observed from Eu2+ on the strontium site present in the lattice. The concentration quenching process between Eu2+ ions is determined and the corresponding concentration quenching mechanism is verified as dipole-dipole interaction. The value of the critical transfer distance is calculated as 25 Å and its reliability is confirmed by using Dexter's theory on energy transfer.
