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.
