Abstract

The synthesis of ZnO:Eu 3+ nanoflowers by a low-temperature hydrothermal route is described. Characterization of the materials was performed by ESEM, XRD and FTIR spectra. The 355 nm excited photoluminescence spectra at 10 K do not indicate the presence of Eu 2+ or the ZnO defect states which give rise to green or red broadband emission. Excitation into the ZnO conduction band at low temperature does not give emission from Eu 3+. Selective excitation of the Eu 3+ emission shows that Eu 3+ ions occupy a variety of different sites, of which one of them is similar to Eu 3+ in C-type Eu 2O 3.
