<p>A light-emitting composition comprising a low molecular weight polyelectrolyte, such as polyethylene oxide, a light-emitting material, a high molecular weight polymer, such as a polymer comprising dialkysiloxane repeat units, such as a dialkylsiloxane-ethylene oxide copolymer, and a salt, preferably wherein the viscosity average molecular weight of the high molecular weight polymer in at least one solvent is at least 5 times greater than the viscosity average molecular weight of the polyelectrolyte, such as polyethylene oxide, in the at least one solvent. The light-emitting composition can be used to provide a light emitting layer 103 in a light-emitting electrochemical cell 100 between an anode 101 and a cathode 105.</p> |
