InAs-GaInAsSbP-InAsSbP double heterojunction light-emitting diodes were fabricated which exhibit electroluminescence near 3.7 mu m at room temperature. Radiative recombination from band-tail states associated with alloy disorder and localized potential fluctuations was observed, as well as emission from states localized at the InAs-pentanary heterointerface.
