چکیده

A new and general approach enabling us to amplify not only the bandgap emission of ZnO nanorods but also the defect emission of Al(2)O(3) is proposed. The light intensity of the band edge emission of ZnO nanorods can be improved by as much as 19 times after the decoration of Al(2)O(3) layers. Moreover, white light emission arising from Al(2)O(3) defects in ZnO/Al(2)O(3) nanostructures also shows a large enhancement factor of 12 times. Our new strategy offers an alternative possibility to create strong white and blue light-emitting devices.

Synthesis and White-Light Emission of ZnO/HfO2: Eu Nanocables

ZnO/HfO(2):Eu nanocables were prepared by radio frequency sputtering with electrospun ZnO nanofibers as cores. The well-crystallized ZnO/HfO(2):Eu nanocables showed a uniform intact core-shell structure, which consisted of a hexagonal ZnO core and a monoclinic HfO(2) shell. The photoluminescence properties of the samples were characterized. A white-light band emission consisted of blue, green, ...
