Summary
This study explores Fano resonances in metallic shell arrays, finding that sphere-like and void plasmon modes interact to create tunable optical properties for potential plasmonic lasing applications.
Area of Science:
- Plasmonics
- Nanophotonics
- Metamaterials
Background:
- Fano resonances arise from the interference of discrete and continuum states.
- Metallic nanostructures support plasmon modes that can exhibit Fano-like behavior.
Purpose of the Study:
- Investigate multiple Fano resonances in 2D hexagonal non-close-packed arrays of metallic shells.
- Explore the tunability of these resonances for plasmonic applications.
Main Methods:
- Numerical simulations of Fano resonance properties.
- Experimental fabrication using colloidal crystal templating.
- Investigation of symmetry breaking effects.
Main Results:
- Observed coexistence of sphere-like and void plasmon modes leading to Fano resonances.
- Demonstrated direct interaction between plasmon modes without symmetry breaking.
- Achieved tunability by altering the inner dielectric core size.
Conclusions:
- Multiple Fano resonances are achievable in metallic shell arrays.
- The structure offers pathways for subwavelength plasmonic lasing with gain materials.

02:37Metallic Solids
Metallic solids such as crystals of copper, aluminum, and iron are formed by metal atoms. The structure of metallic crystals is often described as a uniform distribution of atomic nuclei within a “sea” of delocalized electrons. The atoms within such a metallic solid are held together by a unique force known as metallic bonding that gives rise to many useful and varied bulk properties.
All metallic solids exhibit high thermal and electrical conductivity, metallic luster, and malleability. Many...

02:42Valence Bond Theory
Coordination compounds and complexes exhibit different colors, geometries, and magnetic behavior, depending on the metal atom/ion and ligands from which they are composed. In an attempt to explain the bonding and structure of coordination complexes, Linus Pauling proposed the valence bond theory, or VBT, using the concepts of hybridization and the overlapping of the atomic orbitals. According to VBT, the central metal atom or ion (Lewis acid) hybridizes to provide empty orbitals of suitable...

03:21The Energies of Atomic Orbitals
In an atom, the negatively charged electrons are attracted to the positively charged nucleus. In a multielectron atom, electron-electron repulsions are also observed. The attractive and repulsive forces are dependent on the distance between the particles, as well as the sign and magnitude of the charges on the individual particles. When the charges on the particles are opposite, they attract each other. If both particles have the same charge, they repel each other.
02:42Ionic Crystal Structures
Ionic crystals consist of two or more different kinds of ions that usually have different sizes. The packing of these ions into a crystal structure is more complex than the packing of metal atoms that are the same size.
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...

Crystal Field Theory
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
