a Electroluminescence (EL) spectra of the LEDs with the stacked MQWs structures grown on conventional GaN template (LEDs A) and on nano-ELO bridge GaN template (LEDs B) with injection current at 20 and 80 mA. Inset shows the emission from the LEDs die on the I–V probe stage b Light output power with increasing injection current for EL peak P1 and P2 for LEDs A and B with the image of the LEDs die from optical microscope
