A fluorescent optical fiber is provided that is prepared from a novel material. The novel material comprises a cross-linked polymer Poly(methyl methacrylate) (MMA) [CH.sub.2 .dbd.C(CH.sub.3)COOCH.sub.3 ] and allyl diglycol carbonate (CR-39), initiated with 2.2'-Azo-bis (2 Methylpropionitrile) [(CH.sub.3).sub.2 C(CN)N.dbd.NC(CH.sub.3).sub.2 CN], in which a laser dye or mixture of dyes is dissolved, and the mixture is then thermoset under pressure into Teflon.RTM. tubing. The material exhibits fluorescence when illuminated by various light sources. When the material is formed into a fiber, the result is a fluorescent, large diameter, flexible, light transmitting optical fiber, that emits a lot of side light, presenting a neon-like effect, and can thus be used in illumination applications. Also disclosed is a method of preparation of this novel material into a fiber.
A fluorescent fiber for illumination comprising at least a core, the core being constructed by polymerization of a final mixture, the final mixture being constructed by adding a laser dye and a free radical initiator to an initial mixture, the initial mixture comprising a monomer and a cross-linking agent to cross-link the monomer, the monomer comprising between 35% and 70% by volume of the initial mixture.
A fluorescent fiber for fitting over a cylindrically shaped source of blacklight, comprising:
