Enhancing Eu(3+) magnetic dipole emission by resonant plasmonic nanostructures

We demonstrate the enhancement of magnetic dipole spontaneous emission from Eu ions by an engineered plasmonic nanostructure that controls the electromagnetic environment of the emitter. Using an optical microscope setup, an enhancement in the intensity of the Eu magnetic dipole emission was observe...

Description
Summary:We demonstrate the enhancement of magnetic dipole spontaneous emission from Eu ions by an engineered plasmonic nanostructure that controls the electromagnetic environment of the emitter. Using an optical microscope setup, an enhancement in the intensity of the Eu magnetic dipole emission was observed for emitters located in close vicinity to a gold nanohole array designed to support plasmonic resonances overlapping with the emission spectrum of the ions.
