Abstract
Long wavelength infrared light-emitting diodes have been fabricated from the ternary Pb-chalcogenide material Pb1-xSn,Se with composition x = 3.2%. As captured in an f/2 aperture optical system, these devices emitted approximately 25 nW of 11 Am power with a bandwidth of 0.2 um between half-power points. The line center shifted from 11.6 um at 16 K to 10.4 Am at 50 K, in agreement with results previously obtained from laser emission data. Such devices are useful as radiometric calibration sources for low background infrared detection systems.
