(Color online) PC decay kinetics for InGaAs/GaAs sample with QD at 82 and 290 K. Calculated stretched exponential curve for probe wavelength of 650 nm with τ _dec  = 2.7 ± 0.2 ms, β = 0.53 ± 0.02 at 82 К and τ _dec  = 1.7 ± 0.1 ms, β = 0.38 ± 0.01 at 290 К are shown (a). For probe wavelength of 980 nm, calculated exponential curve with τ _dec  = 0.42 ± 0.02 ms at 82 K and 0.72 ± 0.02 ms at 290 K are shown (b)
