Abstract
Lumiphoric materials and corresponding light-emitting devices, and more particularly localized surface plasmon resonance for enhanced photoluminescence of lumiphoric materials are disclosed. Plasmonic materials are disclosed that are configured to induce localized surface plasmon resonance and excite a corresponding localized surface plasmon enhanced electric field in response to incident light. An increase in photoluminescence of lumiphoric materials may be realized when the lumiphoric materials are arranged within the localized surface plasmon enhanced electric field. Plasmonic materials are disclosed that include various arrangements of nanoparticles and/or patterned structures with corresponding dielectric materials that are collectively arranged in close proximity to lumiphoric materials.
