Abstract :
The aging of II-VI blue-green LEDs, which contain a low density of as-grown extended defects has been examined under room temperature continuous-wave operation at a constant current density of 100 A/cm2. The authors observe a slow decrease in the emission intensity and a monotonic increase in the operating voltage during the device lifetime for more than 350 h
