Abstract

A light-collecting device in the form of, for example, a rectangularly-shaped body having a so-called "fluorescent plate" with at least one light-exit window is comprised of a solid polymerized synthetic carrier material, such as a polyacrylate, a polymethacrylate, polystyrene or copolymer of a methacrylate and a styrene containing fluorescing particles therein which have finite dipole moments with different values in the basic and in the excited state and containing an amphiphilic additive, such as an ionoic or non-ionoic or polymeric soap, with such amphiphilic additive being colloidally dissolved in the synthetic carrier in such a manner that the fluorescing particles are each surrounded by one of the colloid particles and an environment with an orientation polarization is attained whereby the environment can re-orientate so quickly that it achieves its thermodynamic equilibrium substantially completely during the existence of the excited state in the fluorescing particles and tends to suppress the disruptive self-absorption of a light within the fluorescent plate. Such self-absorption originates from a partial overlap of the emission spectrum with the absorption spectrum of the fluorescing particles. In certain embodiments of the invention, an additional polar solvent for the fluorescing particles is also enclosed in the colloid particles. The amphiphilic additive and/or polar solvents can be admixed in the synthetic carrier material and the so-attained system can be cast into a desired body form. The disclosed device is useful as a solar collector, an optical indicia transmitter of an image brightener for passive displays.
