Claim:
1. A dye loaded zeolite composite material, comprising: a plurality of zeolite crystals, each one of said crystals having a proximal face and a distal face opposed therefrom and substantially parallel to said proximal face, each one of said crystals having a plurality of straight through uniform channels extending between the proximal face and the distal face and having a channel axis parallel to and a channel width transverse to a longitudinal crystal axis A, each channel having a proximal channel end located at the proximal face and a distal channel end located at the distal face, said channels containing a substantially linear arrangement of dye molecules, each one of said dye molecules having an elongated shape with a longitudinal extension exceeding a channel width and a lateral extension not exceeding said channel width, and said linear arrangement of dye molecules comprising first dye molecules and second dye molecules, each one of said first and second dye molecules consisting of a chromophore moiety arranged between a pair of terminal moieties, wherein the chromophore moieties of said first dye molecules and of said second dye molecules are substantially identical, but the terminal moieties of said first dye molecules have a lateral extension larger than half of said channel width so that the terminal moieties of said first dye molecules act as spacer elements and energy can be transported from one to the other of two adjacent first dye molecules via FRET (Foerster resonance energy transfer), while the terminal moieties of said second dye molecules have a lateral extension smaller than half of said channel width so that the terminal moieties of said dye molecules allow for the overlap of the terminal moieties of two adjacent second dye molecules and thus enable J-coupling between these adjacent second dye molecules, and said linear arrangement of dye molecules comprises at least one pair of second dye molecules adjacent each other.
