Abstract

A thermal emitter with narrow bandwidth emission property is very useful in the studies of the reaction of biological system to the infrared light. This invention of plasmonic thermal emitter is aimed at providing such narrow bandwidth infrared light emitting source by sandwiching an insulating layer between two metal films and forming regular array of holes in the upper metal to enhance the thermal radiation spectrum of specific wavelengths. Besides, the background thermal radiation can be suppressed by this structure. It was demonstrated that when the central SiO2layer of the sandwiched structure is flat without holes, the emission spectrum is narrower than that of the perforated one. Two emission peaks from Ag/SiO2and Ag/Air surface plasmon polaritons can be clearly seen.
