Photoluminescence (PL), electroluminescence (EL), charge photogeneration and transport were studied in poly(9,9-dihexadecylfluorene-2,7-diyl) (PFC16), poly[(2,5-dihexadecyl-1,4-phenylene)-co-(1,4-phenylene)] (PPPC16) and their blends. Blending of PFC16 with PPPC16 led to a significant improvement of the EL efficiency and stability compared with the devices fabricated from the neat polymers. Efficient blue and white light-emitting devices (LEDs) were fabricated using the blends. The increase in the EL efficiency was attributed to modification of the charge injection, transport and recombination properties in the blend.

Fotoluminescence (PL), elektroluminescence (EL), fotogenerace a transport náboje byly studovány v poly(9,9-dihexadecylfluorene-2,7-diyl) (PFC16), poly[(2,5-dihexadecyl-1,4-fenylene)-co-(1,4-fenylene)] (PPPC16) a v jejich směsích. Míchání PFC16 s PPPC16 vedlo k významnému zlepšení EL účinnosti a stability v porovnání s diodami připravenými z čistých polymerů. Zvýšení EL účinnosti bylo připsáno modifikaci injekce náboje, transportním a rekombinačním vlastnostem blendu.
