Notes: An experimental study concerning the excitation mechanism of the Yb impurity in n- and p-type InP crystals was performed by the method of optically detected microwave-induced impact ionization. Based on the results it is argued that the Yb3+ core excitation is intermediated by a nonradiative recombination of a bound exciton. A fingerprint of the existence of such an excitonic state is given. Also, the nonradiative decay channel is discussed and shown to involve an Auger process with the energy transfer to a locally bound electron. Experimental evidence is presented that by the impact ionization of the bound electron the nonradiative recombination channel may be removed, leading to an increase of the characteristic Yb3+ luminescence. An unprecedented microwave-induced 5% increase of the Yb3+ intrashell emission has been recorded. © 1995 American Institute of Physics.
