ZnSe blue LED with nitrogen-doped ZnSe grown in a Se-rich condition by low-pressure OMCVD

Pure-blue emission of the as-grown ZnSe diode at 300 K was observed. The EL spectrum was dominated by a band-to-band emission peak at 2.68 eV with a half-width 52 meV. The results were consistent with that of the photoluminescence spectrum. These indicated that high-quality ZnSe blue LEDs were obtained under the developed growth condition.
