Description

We have investigated the time-resolved photoluminescence (PL) from anodic aluminum oxide membranes (AAOMs). The PL intensity shows a nonexponential decay, which can be fitted by a stretch-exponential function. Based on the carrier lifetime and the PL emission-energy dependence of the PL decay time, we suggest that the F+-center is responsible for the blue PL in AAOMs. The temperature dependence of the PL lifetime has been explained using a model based on thermally activated nonradiative recombination
