Inorganic Coploymer-Dye Composites and Dye-Doped Mesoporous Materials

Technology Benefits: Enhanced photostability of dyeProcessing of various shapes

Technology Application: Optoelectronic devicesTunable solid-state lasers

Detailed Technology Description: Researchers at the University of California, Santa Barbara have developed a method for preparing transparent mesostructured inorganic/block-copolymer composites or inorganic porous solids containing optically responsive species. These solids have selective optical, optoelectronic, sensing properties and can be processed into a variety of different shapes, such as films, fibers, monoliths, for novel optical and sensing applications. Mesoscopically organized inorganic/block copolymer composites doped with dyes or complexes are prepared for use as optical hosts, chemical/physical/biological sensors, photochromic materials, optical waveguides, tunable solid-state lasers, or optoelectronic devices.

Background

Until now, optically transparent, dye-doped solids have been in the form of large crystals, inorganic glasses, and polymers. In each of these systems, there are limitations to the incorporation of optically responsive compounds or other property restrictions that constrain their utility for device applications. Crystalline solids are limited to low concentration because of disruptions in the crystal lattice, glasses are complicated by low-dye doping levels, and polymeric systems are frequently limited by low thermal and mechanical stabilities, especially with regard to the photostability of the incorporated dye.
