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.
