Efficient manipulation and long-distance transport of single photons is a key component in nanoscale quantum optics. In this Letter, we study the emission properties of an individual light emitter placed into a nanofiber and coupled to a metallic nanoparticle. We find that plasmonic field enhancement together with nanofiber optical confinement uniquely and synergistically contribute to an overall increase of emission rates as well as quantum yields. We predict a quantum yield enhancement up to a factor of 2.5 with respect to free space for an averaged dipole orientation.
