FIG. 2.

Evolution of photoluminescence spectra of the composite of mixed-size CdSe dots and PDMS film under different stretched conditions. Curves a, b, c, and d represent donor-acceptor distance of 37, 41, 46, and , respectively.

Image of FIG. 3.
FIG. 3.

Time resolved photoluminescence decay spectra of small dots (donor) with different conditions. Curve a is in diluted solution. Curve b and curve c are PDMS film with and without stretching, respectively. The inset shows energy dependence of the difference of decay time with and without stretching PDMS film. The decay times were monitored around the photoluminescence spectrum of small dots.

FIG. 4.

Variation of time constant with donor-acceptor distance . The inset shows the calculated energy transfer efficiency as a function of and the solid line is the theoretical result based on Eq. (5).
