OPTICAL COMPOSITION

摘要

The present invention aims to reduce excess scattering in light emitting arrangements. A composition comprising a transparent matrix comprising an anionic organic moiety, and metal cations dispersed in the matrix is disclosed. The anionic organic moiety and the metal cations form an organometallic complex, and wherein the metal cations are capable of forming transparent nano-crystals upon contact with an agent comprising at least one element selected from the group consisting of sulfur and selenium. Also an optical composition comprising a transparent matrix comprising an organic moiety residue, and unmodified nanocrystals is disclosed. Further, a method of preparing an optical composition comprising the steps of: providing a transparent matrix comprising an anionic organic moiety; dispersing metal cations into the matrix; and contacting the organometallic complex with an agent in order to in situ convert at least part of the metal cations into transparent nanocrystals.
