Abstract

The use of polymer light-emitting devices is hindered by their poor stability on exposure to oxygen and moisture as well as by their low quantum efficiency. In the case of blue-light-emitting polymers, an additional major concern is the presence of long-wavelength tails in their emission spectra. With the aim of simultaneously overcoming all these drawbacks, a blue-light-emitting polymer/mesoporous silica nanocomposite was prepared by blending poly(9,9-dioctylfluorene) with nanosized MCM-41. This nanocomposite film shows dramatically increased photostability and colour purity, as well as higher electroluminescence output.
