19_01/2007Cover Picture: Imaging the Fluorescence Decay Lifetime of a Conjugated-Polymer Blend By Using a Scanning Near-Field Optical Microscope (Adv. Mater. 1/2007)

The cover image shows the surface topography of a phase-separated blend of two conjugated polymers. On p. 107, Lidzey and co-workers show that the fluorescence decay lifetime of a conjugated polymer in such a blend can vary significantly between the different phase-separated domains. This variation results in a marked dependence of the photoluminescence quantum efficiency on the relative blend composition.
