Broadly speaking, embodiments of the present invention provide a solid state light-emitting device and a method of manufacturing the solid state light-emitting device. The method comprises preparing a thin layer of semiconducting perovskite nanoparticles embedded in a matrix or blend of a material that has a wider band gap than the semiconducting perovskite nanoparticles. In embodiments, the method comprises blending a solution of a semiconducting perovskite material or a precursor therefor with a solution of a material that has a wider band gap than the semiconducting perovskite material or a precursor therefor followed by removal of the solvent from the mixture thus formed, to give the semiconducting perovskite nanoparticles embedded in a matrix or blend of the material that has a wider band gap than the semiconducting perovskite nanoparticles.

Electroluminescent device

A switchable electronic device comprises a hole blocking layer and a layer comprising a conductive material between first and second electrodes, wherein the conductivity of the device may be irreversibly switched upon application of a current having a current density of less than or equal to 100 A cmto a conductivity at least 100 times lower than the conductivity of the device before switching. The conductive material is a doped organic material such as doped optionally substituted poly(ethylene dioxythiophene).

Switchable electronic device and method of switching said device

Provided is a method of fabricating an organic light-emitting device; which method comprises the steps of: forming a first electrode () for the device over a substrate (); either forming by self-assembly at least one polymer layer () over the first electrode () and forming other than by self-assembly at least one layer of organic light emissive material () over the at least one polymer layer (); and forming a second electrode () for the device over the at least one layer of organic light emissive material (); or forming other than by self-assembly at least one layer of organic light emissive material over the first electrode and forming by self-assembly at least one polymer layer over the at least one layer of organic light emissive material; and forming a second electrode for the device over the at least one polymer layer. Also provided is an organic light emitting device, obtainable according to the method of the present invention.

Manufacture of electroluminescent devices

Electroluminescent device comprising a chromophoric polymeric composition

This invention provides semiconductive conjugated polymers incorporating electron-withdrawing groups for use in electroluminescent devices, methods for their manufacture, and electroluminescent devices incorporating the polymers. The electron-withdrawing group is conjugatively linked to the polymer chain and is selected so that the polymer exhibits electroluminesence upon application of an electric field to a layer thereof.
