| 摘 要： | Co(Ⅱ) doped Zn Te nanowires are prepared by a thermal evaporation method. The power and temperature dependent micro-photoluminescence spectra of single nanowire demonstrate the double bands near its band edge,and the ferromagnetism behavior for these nanowires is identified. The occurrence of excitonic magnetic polaron(EMP) can account for the second emission band for its higher binding energy and ferromagnetic coupling. This EMP formation in a nanostructure will facilitate to realize magnetic modulation on confined excitons and will find new applications for spinpolarized nanophotonic devices.
