摘要

We report the cathodoluminescence (CL) study of boundexciton- polaritons in ZnO whispering gallery (WG) microcavity. Thanks to the very high spatial resolution (: 100 nm) of CL technique, a scanning CL mapping along the tapered ZnO nanowire is achieved. We observe a clear anticrossing behavior which demonstrates the strong coupling between cavity mode and bound-excitons. Coupled oscillator model including both bound excitons and free excitons fits well with the experimental results. The energy splitting of bound-exciton-polaritons:2.6 meV is obtained.
