Abstract :
The paper reports on influence of the emission wavelength on characteristics and performance of high-power light-emitting diodes (LEDs) emitting light in the near-UV (370 nm) and green (530 nm) spectral ranges and having a similar chip design. Similarity and difference in operation of the LEDs is revealed by their detailed characterization. The correlations between the device characteristics and properties of materials used for the LED fabrication are discussed.
