20080213535Oriented Zeolite Material and Method for Producing the Same - An oriented zeolite material comprises a plurality of zeolite crystals (09-04-2008
20110094566Luminescence Concentrators and Luminescence Dispersers on the Basis of Oriented Dye Zeolite Antennas - 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.04-28-2011

20100003188METHOD FOR INTERCALATING CHROMOPHORES INTO ZEOLITE-L NANOCHANNELS AND PRODUCTS THEREOF - The present invention discloses a method for the intercalation of a chromophore within channels of a zeolite L crystal. The intercalated chromophores exhibit J type aggregation of the chromophores within the channels of the zeolite L crystals. The invention discloses method parameters which lead to the J type aggregation of the chromophores within the channels of the zeolite L crystals. The J type aggregation of the chromophores affords unique florescent properties rendering the intercalated zeolite L crystals as a material for use in novel optoelectronic devices.01-07-2010

20110287408Preparation of Micro-Porous Crystals and Conjugates Thereof - A conjugate comprising a dye-labeled microporous crystal, a stop-cock moiety, and covalently bound thereto an affinity binding agent is disclosed. The dye-labeled microporous crystal is a zeolite crystal, such as a zeolite L crystal, having a large number of channels in its interior into which the dye is loaded. The stop-cock moiety can be functionalized with an amino group to which a carboxyester group can be attached. The affinity binding agent allows for the binding to a biological moiety. The conjugate of the moiety can be used in in-vivo and/or in-vitro imaging applications.11-24-2011
