The effects of mid-infrared (MIR) radiation on the photoluminescence (PL) of Yb3+ in p-type InP have been investigated in the wavelength range of 7-17 µm. It has been found that effective quenching of the luminescence intensity can be observed during the 4 µs length of the MIR pulse. The effect is explained by an Auger process of energy transfer between the Yb3+ excited state and free holes that are ionized from the acceptors in the host. From the dependence of the luminescence quench amplitude on the MIR wavelength, the acceptor is identified as Zn, which is the residual acceptor in the investigated sample. © 2001 Elsevier Science B.V.
