    摘要： Perovskite luminescent crystal composition comprising perovskite luminescent crystals bearing a polymeric surface ligand having a molecular weight of at least 700 g/mol, wherein the polymeric surface ligand is a polymer comprising a backbone and side chains, wherein at least one side chain comprises at least one functional group selected from amines, carboxylates, phosphates, thiols or combinations thereof, wherein the binding of the perovskite luminescent crystals to the surface ligand occurs through the surface ligand's functional groups, thereby forming a perovskite luminescent crystal-ligand complex, and wherein the perovskite luminescent crystal-ligand complex is embedded in a polymer.

    摘要： A light emitting component comprising a first light source (11) for emitting blue light (aa), a second light source (12) for emitting red light (bb), and a luminescent layer (100) comprising a solid polymer composition and green luminescent crystals (1). The solid polymer composition comprises a polymer (2). The green luminescent crystals (1) are perovskite crystals. The first (11) and the second (12) light source are directed to the luminescent layer (100). Upon absorption of the light emitted by the first light source (11), the luminescent crystals (20) emit light of a wavelength in the green light spectrum (cc) .

    摘要： The invention relates to a process for producing a crystalline A/M/X material, which crystalline A/M/X material comprises a compound of formula [A] a [M] b [X] c wherein: [A] comprises one or more A cations; [M] comprises one or more M cations which are metal or metalloid cations; [X] comprises one or more X anions; a is a number from 1 to 6; b is a number from 1 to 6; and c is a number from 1 to 18. The process is capable of producing crystalline A/M/X materials while precisely controlling their stoichiometry, leading to products with finely tunable optical properties such as peak emission wavelength. The invention also relates to process for producing a thin film comprising the crystalline A/M/X material of the invention, and to a thin film obtainable by the process of the invention. An optoelectronic device comprising the thin film is also provided.
