The interactions between surface plasmons in metal nanostructures and excitons in quantum emitters lead to many
interesting phenomena that are strongly dependent on the quantum yield of surface plasmons. The experimental
measurement of this quantum yield is hindered due to the difficulty in distinguishing all the possible exciton
recombination channels. By utilizing the propagation of surface plasmons, we experimentally measured the decay rates
of all exciton recombination channels, and thus obtained the quantum yield of single surface plasmons generated by a
quantum dot coupled with a silver nanowire.
