This illustration shows what happens in nitride-based LEDs. At left, an electron (negative) and electron hole (positive) recombine and release light (left). In Auger recombination (right) the electron and hole combine with a third carrier, releasing no photon in the process. In this case, the energy loss is also assisted by indirect processes, vibrations in the crystal lattice shown as squiggles.
