Erratum: “Förster energy transfer from blue-emitting polymers to colloidal $CdSe∕ZnS$ core shell quantum dots” [Appl. Phys. Lett. 85, 4169 (2004)]

Due to an error in the preparation of the manuscript, the solutions of Eqs. (2) and (3), reported in the paper and used in the data fitting, are not correct. We report the correct fitting functions and the revised results of the time resolved data. The error removal leads to a decrease of the Förster radius extracted from the time resolved PL from $R0=80±15Å$ to $R0=48±3Å$⁠, which is closer to the one extracted from the spectra $(R0=56±2Å)$⁠, thus strengthening the general conclusions of the paper. The best fit acceptor decay time is also reduced from about $τA=220±10ps$ to $τA=145±10ps$⁠.

The fitting function for the donor PL is

with $fi=Ai∕(A1+A2)$⁠.

Good agreement between the best fit curves and the experimental data is still obtained (see Fig. 3) with $fi$ and $τDi$ fixed to the PDFC best fit values, and with a maximum $β=(2.2±0.2)10−2ps−1∕2$ (see Table I) for sample S5, corresponding to a Förster radius $R0=48±3Å$⁠, which is close to the value extracted from the spectra $(R0=56±2Å)$⁠. The solution of Eq. (3), if $1∕τ′=1∕τD−1∕τA>0$ is

where $nD0$ is the initial donor population. If $1∕τ′<0$⁠, the solution is

with $Ierf(x)=erf(ix)∕i$⁠. The best fits (see Fig. 4) of the dot relaxation dynamics are obtained by fitting the data to a linear combination of $n1A$ and $n2A$ with relative amplitudes $f1$ and $f2$⁠, in order to take into account of the polymer biexponential decay, with $τA=145±10ps$⁠, and $f1,f2,τ1,τ2,$ and $β$ fixed to the donor best fit values.
