Here we develop a new solution-processed electroluminescent source emitting at 5m. Our light-emitting diode is based on integrating the cascade intraband electroluminescence of HgSe/CdS colloidal quantum dots with resonant plasmonic bowtie antennas. The bowtie provides the electrodes and the cavity for Purcell enhancement。
