The Rapid Research Letter on p. 199 ff. has been written by Jacques Lefebvre et al. from the Institute for Microstructural Sciences of the National Research Council, Ottawa (Ontario), Canada. This article reports two distinct modes of electroluminescence (EL) from a single‐walled carbon nanotube (SWNT) network in field effect transistor geometry at various bias voltages. It is of pivotal importance to probe and understand the nature of such findings. Usually the spectral emission is broadband consistent with blackbody radiation due to Joule heating, but in rare cases a narrow linewidth is observed superimposed on the broad background. This narrow emission is evidence for electrical excitation and recombination in a process similar to photoluminescence. Obviously, the narrow EL bears promise for SWNT based optoelectronics.
