Synthesis of Eu2O3 nanowire arrays through a facile sol–gel template approach

摘要

Eu2O3 nanowire arrays embedded in anodic alumina membranes (AAMs) were fabricated by an improved sol–gel method. They have cubic structures with uniform diameter of about 40 nm. The emission spectra of Eu2O3 consist of one main line at 613 nm under 377 nm excitation, which shows the electric dipole transition 5D4→7F5 (at 613 nm) is the strongest.
