Abstract

Read online

A new composite consisting of ZnO nanorods and SnO nanoparticles has been synthesized and characterized. It is found that the UV laser emission from ZnO NRs can be greatly enhanced and more easily achieved by the assistance of SnO NPs. The underlying mechanism is interpreted in terms of light scattering, charge carrier transfer and fluorescence resonance energy transfer (FRET) mediated by SnO NPs. Our strategy opens a promising route for improving the external conversion efficiency of optoelectronic devices.
