Abstract
Room‐temperature long‐wavelength (4.6‐μm) light emitting diodes have been fabricated from high quality lead‐sulfide‐selenide single crystals. Spontaneous emission spectra were used to determine the temperature dependence of the band gap. The result (3.9×10−4 eV/K) is in good agreement with data obtained by others. The bandwidth of the emission is proportional to temperature. These results suggest that thermally broadened band‐to‐band recombination is the source of electroluminescence.Keywords
