Abstract

Fiber draw synthesis process. The process includes arranging reactants in the solid state in proximate domains within a fiber preform. The preform is fluidized at a temperature below the melting temperature of the reactants. The fluidized preform is drawn into a fiber thereby bringing the reagents in the proximate domains into intimate contact with one another resulting in a chemical reaction between the reactants thereby synthesizing a compound within the fiber. The reactants may be dissolved or mixed in a host material within the preform. In a preferred embodiment, the reactants are selenium and zinc.
