Abstract :
Summary form only given. Tunable mid-infrared light is an efficient tool for probing molecular structures and medium energy bondings in various materials. Cr2+-dopped ZnSe is widely used for diode-pumped laser operation in the 2-3mum wavelength range. Due to its electrical properties, this material is also identified as a good candidate for electrically pumped emission. We report mid-infrared electroluminescence observed at room-temperature from a bulk ZnSe:Cr single crystal.
