Abstract  

The green light emitting diodes (LEDs) have lower quantum efficiency than LEDs with other emission wavelengths in the visible spectrum. In this research, a novel quantum well structure was designed to improve the electroluminescence (EL) of green InGaN-based LEDs. Compared with the conventional quantum well structure, the novel structure LED gained 2.14 times light out power (LOP) at 20-mA current injection, narrower FWHM and lower blue-shift at different current injection conditions.
