Ag nanowires have attracted much attention due to their potential applications in spontaneous emission amplifiers,logic gates, single photon sources, and biomolecule detection. Single crystal Ag nanowires are prepared by chemical method. The Ag nanowires exhibit pentagonal cross sections with an average radius of 80 nm. Two enhanced emission peaks(345 and 383 nm) are observed in Zn O quantum dots when mixing with Ag nanowires. To explore the origination of the enhancement, the localized surface plasmon reso...
