CHANGE OF DYNAMIC CHARACTERISTICS AND QUANTUM EFFICIENCY OF ELECTROLUMINESCENCE SPECTRA COMPONENTS OF InGaN BASED LEDs DURING ACCELERATED TEST
The results of accelerated tests of green InGaN based LEDs under the effect of temperature and high-density pulsed current are presented. It is established that the quantum efficiency of the short-wave region of the spectrum falls off by a larger amount than the quantum efficiency of the long-wave region of the spectrum. The lifetime of charge carriers during radiative recombination increases monotonically, while the nonradiative lifetime decreases monotonically in all regions of the electroluminescence spectrum.
