Photoluminescence of Eu(III)-Doped ZnO Nanopowder and Energy Transfer from ZnO to Eu(III) Ions

Abstract

An europium(III)-doped ZnO (ZnO:Eu3+) nanopowder has been directly synthesized by a high-temperature calcination method. Under the typical UV ZnO excitation, Eu3+-doped samples exhibit strong red luminescence from Eu3+ ions with complete quenching broad emission. An energy transfer from ZnO host to Eu3+ ions can be observed.
