Abstract
Blue light emitting devices are of special value in optical recording, information processing, display and undersea applications. Recently, ZnSe has been shown to be a promising material for making such devices with reports of pulsed ZnSe based diode lasers at low temperature [1] and light emitting diodes (LEDs) at room temperature (RT) [2][3]. However, efficient and reliable operation of these device types at RT has yet to be demonstrated. In this work, we study the temperature dependence of the output spectral features and current-voltage (I-V) relations of ZnSe LEDs. The results may prove useful for developing efficient/reliable blue LEDs and lasers.
