摘要：

The time dependence of the internal 4f-4f transitions of Yb**3** plus in InP has been studied as a function of temperature over the range 10 to 110K. The quenching of both the photoluminescence intensity and the excited state lifetime is found to be thermally activated with E//A approximately equals 0. 1 ev. This is interpreted in terms of hole emission from the neutral Yb acceptor. At low temperature the lifetime appears dominated by weak coupling to resonant states in the valence band, while nonexponential contributions to the decay are interpreted as being due to the capture of nonequilibrium carriers by the neutral Yb acceptor.
