“…With a detection limit for the coefficient (Y of cm", we can estimate from Dexter's formula for absorption of localized defects C331 an absolute upper limit for the optically active defect concentration of lo1* cm". SIMS investigations on these samples determined total Yb concentrations in the range of 3 x lo1' to 1.5 x 1019 cm" [34], which for several of our samples is clearly more than the upper bound to the number of optically active Yb centres. Second, since some samples with low Yb concentrations gave 4f PL signals of the same strength as those with high concentration, we conclude that only a (small?)…”

The excitation and decay mechanisms of the Yb3+ intra-4f-shell emission are studied in n-type Mow-grown and p-type LPE grown InP:Yb layers by photoconductivity measurements, time-resolved photoluminescence, photoluminescence excitation and emission spectroscopy. Assuming a pseudodonor or pseudo-acceptor-like character of the isoelectronic Yb3+ T,, centre the temperature dependences of the 41-shell transition intensity and lifetime can be consistently explained. Models for the excitation and decay processes of the Yb3+ photoluminescence are proposed.
