Electroluminescent devices having nanostructure-film electrode(s)
View Patent ↗An electroluminescent (EL) device is described, comprising an EL material, an electrode and nanostructures. The nanostructures may form an interconnected network, and may be employed in the EL material and/or in the electrode. A second electrode is also described, wherein an electric field formed between the two electrodes excites phosphors in the EL material to produce light.
1. An electroluminescent (EL) device, comprising:
an EL material including a phosphor material;
a first electrode; and
a second electrode, wherein at least one of the first and second electrodes comprises a nanostructure film, the nanostructure film including at least one interconnected network of carbon nanotubes, open porosity in the nanostructure film being filled with the EL material, the nanostructure film having a sheet resistance of less than about 920 ohms/sq.
2. An electroluminescent (EL) device, comprising:
an EL material including a phosphor material;
a first electrode; and
a second electrode, wherein at least one of the first and second electrodes comprises a nanostructure film, the nanostructure film including at least one interconnected network of carbon nanotubes, open porosity in the nanostructure film being filled with the EL material, the nanostructure film having a sheet resistance of less than about 230 ohms/sq.
3. An electroluminescent (EL) device, comprising:
an EL material including a phosphor material; and
a first electrode comprising a nanostructure film, the nanostructure film including at least one interconnected network of carbon nanotubes, open porosity in the nanostructure film being filled with the EL material, the interconnected network having a sheet resistance of less than about 920 ohms/sq.
4. The EL device of claim 3 , further comprising a second electrode.
