Description

Time resolved photoluminescence (PL) measurements of the internal 4f-4f transitions of Yb/sup 3+/ have been carried out in InP and GaP. In InP a nonexponential component is observed in the PL decay, and is interpreted in terms of carrier capture by nonequilibrium Yb/sup 3+/. At low temperatures the exponential component is found to be much faster (∼ 12.5 μsec) than expected, and is tentatively associated with a weak coupling to resonant valence band states. As the temperature is increased, the PL intensity and the exponential component of the excited state lifetime are quenched with a thermal activation energy of ∼0.1 eV. This is interpreted as being due to the emission of a hole into the valence band by the neutral Yb acceptor
