Abstract
The excitation and decay mechanisms of the Yb3+ 4f-4f intra-shell emis sion in InP and InAsP (4% and 7% of As) are analysed. Exciton binding by Yb ion is discussed. The photoluminescence transient measurements i ndicate that the Yb PL emission is deactivated at increased temperatur e by energy back-transfer to band states of InP and InAsP.
