Abstract

A device comprising: two mutually immiscible conductive liquids arranged to form an interface therebetween; a plurality of nanoparticles localised at the said interface, the said nanoparticles each having a first region formed of a semiconductor having a first bandgap, the first region being surrounded by a second region having a second bandgap, the second bandgap being larger than the first bandgap; and means for applying an electric field to the said nanoparticles and thus, through the Stark effect, altering the optical absorption or emission characteristics of the nanoparticles.
