A Scanning Tunneling Microscope (STM) is used to excite individually localized plasmons in the tunneling gap between the probe tip and small supported silver particles. A blue shift of the maximum of the resonance when the thickness of the crystallite is decreased down to the nanometer is reported and explained in the framework of existing models.
