Characterizing plasmonic properties via electron energy loss spectroscopy.

Main Results:

Successfully formed gold nanoparticle chains with metallic junctions.
Silver bridges induced a significant red shift of longitudinal plasmon modes into the mid-infrared.
Palladium addition caused a red shift with substantial plasmon damping.

Conclusions:

The developed method enables precise engineering of plasmonic hot spots.
The choice of the bridging metal (silver or palladium) tunes the plasmonic response.
This approach offers a pathway to design custom plasmonic structures for specific applications.
