title: Ag nanowires enhanced upconversion emission of NaYF4:Yb,Er nanocrystals via a direct assembly method.
abstract: Enhanced upconversion emission of NaYF(4):Yb,Er nanocrystals with Ag nanowires was observed; the enhancement factor of red emission is larger than that of green emission, and it can be further increased with Ag islands composed of larger Ag particles.
