Image of FIG. 1.
FIG. 1.

(Color online) Excitation-energy dependence of the PL intensity in the d = 40 and d = 20 nm samples (Ref. 12). The dotted curves indicate the PL spectra of the spacer layer.

Image of FIG. 2.
FIG. 2.

(a) Excitation-energy dependence of the PL decay profiles in the d = 40 nm sample. Detection energy is the PL peak energy of the sample. Excitation energy at 1.90 eV corresponds to the excitation of higher states. (b) PL decay time plotted as a function of excitation energy.

Image of FIG. 3.
FIG. 3.

Excitation-density dependence of the PL decay time in the d = 40 nm sample.

Image of FIG. 4.
FIG. 4.

Detection-energy dependence of the PL decay time. Closed and open circles indicate the results for excitation at 1.90 and 1.55 eV, respectively.

Image of FIG. 5.
FIG. 5.

(Color online) Numerical simulation of the PL decay profiles described by Eq. (3). (a) For various C 2 under γ 1 < γ 2, (b) for various C 2 under γ 1 > γ 2, and (c) for various γ 2 under C 1 = C 2. Open circles represent the numerically reproduced experimental results.

Image of FIG. 6.
FIG. 6.

PL decay time evaluated by fitting with a single exponential function form plotted as a function of excitation energy in the d = 20 nm sample. The detection energy is the PL peak energy.
