Enhancement of Thermal Radiation in Plasmonic Thermal Emitter by Surface Plasmon Resonance


The emission spectra of Ag/Si02/Ag tri-layer plasmonic thermal emitters were investigated. It is demonstrated that the top silver film perforated with periodic hole arrays plays a role to amplify the thermal emission in the emitter at a specific wavelength determined by the surface plasmon. Obviously the amplification of the thermal radiation is independent… (More)
