<p>An emissive element for a device (700) for emitting electromagnetic radiation is disclosed. The emissive element comprises at least one emissive layer (706) including at least one organic material, and a plurality of interconnect islands (703, 704) embedded in at least one predetermined said emissive layer and separated from each other. Each of a plurality of said interconnect islands comprises respective electron injecting means (703A, 704A) and respective hole injecting means (703B, 704B), wherein at least one emissive domain is defined by at least part of said electron injecting means of a respective first said interconnect island, at least part of said hole injecting means of a respective second said interconnect island adjacent said first interconnect island and a respective region of said emissive layer separating said electron injecting means and said hole injecting means. Application of a suitable electric field to the emissive layer in use in a device for emitting electromagnetic radiation causes electron injecting means and hole injecting means of at least one said domain to supply electrons and holes respectively, to cause said at least one said emissive domain to emit electromagnetic radiation.</p> |
