Energy transfer dynamics in blended conjugated polymer nanoparticles (CPNs) were investigated in order to further our understanding of photoswitching and anomalous saturation behavior we previously observed, and as a way to probe the complex energy transport processes occurring in similar systems of interest such as nanostructured bulk heterojunction photovoltaic devices. We prepared blended poly[(9,9-dioctylfluorenyl-2,7-diyl)-co-(1,4-benzo-{2,1′,3}-thiadiazole)] (PFBT)/poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene] (MEH-PPV) nanoparticles with varying blending ratios. Efficient energy transfer from PFBT to MEH-PPV was observed, yielding bright, red-shifted emission. The donor exhibited complex decay kinetics consistent with energy transfer in complex, nanoscale, multichromophoric systems. The fluorescence decay kinetics and steady-state quenching efficiencies are compared to a multiple energy transfer model and prior results for dye-doped nanoparticles. The analysis indicates that the high en...
