Abstract
A luminescent component includes a first element comprising a first solid polymer composition, wherein the first solid polymer composition includes first luminescent crystals, wherein the first luminescent crystals are of the perovskite structure, and are selected from compounds of formula (I): MMX, wherein Mrepresents Cs, optionally doped with up to 30 mol % of one or more other metals having coordination number 12, Mrepresents Pb, optionally doped with up to 30 mol % of one or more other metals having coordination number 6, X independently represents anions selected from the group consisting of Cl, Br, I, cyanide, and thiocyanate. The first luminescent crystals are of size between 3 nm and 3000 nm, and emit light of a first wavelength in response to excitation by light with a wavelength shorter than the first wavelength. An encapsulation including a polymer or an inorganic matrix encloses the first element.
