FIG. 1.

Schematic diagram of the energy levels and the transition rates. States , , and the dark state represent the nanocrystal ground state, the confined exciton state and the charged fluorescence off state, respectively.

FIG. 2.

Photoluminescence intensity as a function of time. Time axis is scaled by , , and . Blue, black. and red lines correspond to , , and . Solid lines are obtained by the inverse Laplace transformation of Eq. (8) by the Stehfest method (Ref. 11). The dashed lines are the asymptotic power law decay given by Eq. (14).

Photoluminescence intensity as a function of time. Time axis is scaled by , , , and . The solid line is obtained by the inverse Laplace transformation of Eq. (8) by the Stehfest method (Ref. 11). The dashed line is the asymptotic power law decay given by Eq. (14). The shaded region shows the region over which the experimental data on the fluorescence intensity from a single crystal of bare CdSe which are taken from the second curve from the top in Fig. 1(a) of Ref. 2 are scattered, where is assumed to be 1 ns.
