Ultra-narrow-band near-infrared thermal exciton radiation in intrinsic one-dimensional semiconductors
Abstract
Narrow-band thermal emitters are still scarce despite their potential for infrared energy conversion applications. Here the thermal emission of one-dimensional carbon nanotubes up to 2000 K is reported to exhibit very narrow excitonic emission with a full-width at half-maximum of approximately 170 meV.
