Luminescence spectra of blue and green LEDs based on InxGa₁₋xN/AlyGa₁₋yN/GaN heterostructures with many quantum wells in the current range 0.1 to 10 mA have been studied besides the main electroluminescence band. In the emission spectra of blue LEDs, the energy maximum position is shifted with chang...
