Abstract: Disclosed are a perovskite color converter and a method for manufacturing the same. In order to maintain strong physical properties, the siloxane resin is synthesized in two steps. The silane precursor performs siloxane bond through a non-aqueous sol-gel reaction to form a siloxane resin, and a bond between methacrylate group, and a bond between methacrylate group and an organic ligand are formed through a secondary cross-linking reaction.

Abstract: The present invention relates to a method for preparing a semiconductor nanocrystal siloxane composite resin composition, and a cured product using the same. In the preparation method, the semiconductor nanocrystals are added during a non-hydrolytic sol-gel condensation reaction for forming a siloxane structure so that a siloxane resin having a dense inorganic network, which includes a siloxane bond, is encapsulated and thus is dispersed in the semiconductor nanocrystals through a chemical interaction and a chemical bond, thereby preventing a reduction in inherent characteristics (quantum efficiency) of the semiconductor nanocrystals resulting from an external oxidizing environment. Accordingly, when the curing of the resin composition is carried out, a cured product, which can be applied to various applications including a semiconductor nanocrystal siloxane composite having excellent reliability, can be provided.
