摘要： 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.
