摘要：

Photoluminescence and electroluminescence (EL) of poly(9,9-dihexadecylfluorene-2,7-diyl) (PFC16) and its blends with hole-transporting poly[methyl(phenyl)silanediyl] modified with pyrene were studied. Efficient blue light-emitting devices were fabricated. Blending of PFC16 with modified polysilane led to a significant improvement in the EL efficiency and stability compared with the devices fabricated from neat PFC16. An increase in the EL efficiency of up to two orders of magnitude was achieved. The increase in the EL efficiency was attributed to the modification of the charge transport and recombination in the blend. (C) 2003 American Institute of Physics.
