description | <p>Abstract</p> <p>ZnO/HfO<sub>2</sub>:Eu nanocables were prepared by radio frequency sputtering with electrospun ZnO nanofibers as cores. The well-crystallized ZnO/HfO<sub>2</sub>:Eu nanocables showed a uniform intact core–shell structure, which consisted of a hexagonal ZnO core and a monoclinic HfO<sub>2</sub> shell. The photoluminescence properties of the samples were characterized. A white-light band emission consisted of blue, green, and red emissions was observed in the nanocables. The blue and green emissions can be attributed to the zinc vacancy and oxygen vacancy defects in ZnO/HfO<sub>2</sub>:Eu nanocables, and the yellow–red emissions are derived from the inner 4f-shell transitions of corresponding Eu<sup>3+</sup> ions in HfO<sub>2</sub>:Eu shells. Enhanced white-light emission was observed in the nanocables. The enhancement of the emission is ascribed to the structural changes after coaxial synthesis.</p> |
