PL decay curves and decay time constants. (a) PL decay curves (taken at the maximum of PL emission) for samples annealed at three different temperatures. There is a clearly visible influence of the annealing temperature on the decay rate. Lines represent single exponential fit. (b) Decay time constants for all structures.
