摘要：

Light-emitting diodes based on blends of two polyfluorene copolymers with the host poly(9,9-dioctylfluorene), PFO, exhibit a significantly higher efficiency in comparison to the devices fabricated with the neat copolymers. This improvement is mainly attributed to a combination of efficient energy transfer and spatial exciton confinement within the guest copolymer chains.
