Nonradiative

He had done that in virtue of having followed out to their logical issue the fundamental scientific principles of the subject which he had so clearly grasped, one of which was the essential distinction between the radiative and the nonradiative circuit.

Multi-charge centers and complexes in semiconductors may represent effective centers for nonradiative recombination due to Auger processes involving participation of two localized carriers.

A nonradiative transition then occurs by recombination of a free hole with this trapped electron, the excess energy being transferred to the lattice.
