Abstract

The temperature dependence of ESR in InP:Er and the O-2 codoping effect inInP:Er have been studied by X-band ESR measurement at low temperature. TheESR at around g = 6, which corresponds to Er3+ site with T-d symmetry, lost it's intensity quickly as the temperature is increased and disappeared above 12 K, The temperature dependence of the integrated intensity turned outto be different from simple Curie law. The intensity of the ESR at around g = 6 decreased as O-2 is codoped into InP:Er. No new ESR was observed in O-2 codoped InP:Er in contrast to the results of O-2 codoped GaAs:Er. These results are discussed in connection with the O-2 codoping effect of photoluminescence spectra. (C) 2001 Elsevier Science B.V. All rights reserved.
