  We report on the experimental and theoretical study of the spatial
fluctuations of the local density of states (EM-LDOS) and of the fluorescence
intensity in the near-field of a gold nanoantenna. EM-LDOS, fluorescence
intensity and topography maps are acquired simultaneously by scanning a
fluorescent nanosource grafted on the tip of an atomic force microscope at the
surface of the sample. The results are in good quantitative agreement with
numerical simulations. This work paves the way for a full near-field
characterization of an optical nanoantenna.
