Abstract: The electroluminescence spectra of high-power light-emitting diodes (LEDs) based on p – n heterostructures of the InGaN/AlGaN/GaN type emitting in the visible short-wavelength and ultraviolet spectral regions (the range from 370 to 460 nm) are investigated. The shape of spectra is described by a model taking into account a two-dimensional combined density of states and potential fluctuations. Additional long-wavelength peaks are found in emission spectra. The emission power of ultraviolet and violet LEDs reaches 233 mW at a current of 350 mA, and the external quantum yield reaches 23% at the maximum (near a current of 100 mA).
Keywords: Violet LEDs, Electroluminescence Spectra, High-power LEDs, External Quantum Yield, Potential Fluctuations.
