Patent ID: 8917969

Claim:
A device for concentrating light, as a luminescence concentrator, or for dispersing light, as a luminescence disperser, consisting of luminescent sites, which are formed from donor and acceptor dye molecules in a donar/acceptor ratio greater than 10:1 in supramolecular arrangement and organized in zeolites so as to result in an antenna function, which luminescent sites are referred to as antennas, wherein no dye molecules are present on the outer surface of the zeolites which are embedded as one layer, or two or more layers spaced apart, into a polymer, individual dye-zeolite layers having a thickness between 10 nm and 2000 nm, and which are on or between transparent sheets which are suitable for total internal reflection and consist of glass, plastic or a combination thereof, wherein the thickness of the sheets is of the order of magnitude of one or more of these layers.
