Novel materials and methods for dispersing nano particles in matrices with high quantum yields and stability

A process for the production of a solid polymer with embedded luminescent nano particles, the process comprising:

• mixing luminescent nano particles with an outer surface coated with capping molecules, the capping molecules comprising a first functional group and a second functional group;
• with a precursor of the solid polymer, and
• allowing the solid polymer to be formed, thereby producing the solid polymer with embedded nano particles;
• wherein the first functional group is configured to bind to the outer surface of the quantum dot and wherein the second functional group has one or more functions selected from the group consisting of being miscible with the precursor of the solid polymer and being able to react with the precursor of the solid polymer,
• wherein the capping molecules comprise two types of capping molecules, wherein the first functional group of the first type of capping molecules comprises a metal ion having a coordinating functionality, and wherein the first functional group of the second type of capping molecules has a Lewis base functionality.
