We have demonstrated a Eu-doped GaN(GaN:Eu) red light-emitting diode (LED) operating with low voltage. However, light output has been still insufficient for practical use. To enhance the light output, I designed the LED with multiple quantum blocking layer(MQB) for electron blocking layer(EBL). The result shows that the light output of LED with MQB EBL is higher than LEDs with Single EBL and without EBL.
