Abstract

A dye loaded zeolite composite material comprises a plurality of zeolite crystals each 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 contains a substantially linear arrangement of dye molecules comprising first and second dye molecules having an elongated shape with a longitudinal extension exceeding said channel width and a lateral extension not exceeding said channel width. Each dye molecule consists of a chromophore moiety arranged between a pair of terminal moieties, wherein: the chromophore moieties of the first and second dye molecules are substantially identical, the terminal moieties of the first dye molecules have a lateral extension larger than half of the channel width, the terminal moieties of the second dye molecules have a lateral extension smaller than half of the channel width, the linear arrangement of dye molecules comprises at least one pair of second dye molecules adjacent each other.

Abstract

A luminescence concentrator (LK) may concentrate both incident direct and diffuse light by way of frequency shift and total internal reflection. It differs fundamentally from geometric concentrators. With sufficient geometric expansion of the collector plate, nearly arbitrarily high concentration can be achieved in the LK. A luminescence disperser is an apparatus which holds both directional and nondirectional incident light captive in a transparent body by way of frequency shift and total internal reflection and emits it diffusely or directionally uniformly distributed across an area by way of luminescence emission. The object of the invention is a method for the technical implementation of the LK and luminescence disperser, using zeolite crystals having a nanotube structure, into which the luminescent dyes are embedded such that they have antenna properties. Using the resulting novel structures, problems can be solved which made the technical use of LK impossible or at least considerably limited it. This results in completely novel usage possibilities for collecting and concentrating sun light and feeding it into photovoltaic systems, for converting it into electric and thermal energy in combined photovoltaic/hot water apparatuses, and for feeding it into fiber optic apparatuses.
