Fabrication and Photostability of Rhodamine-6G Gold Nanoparticle Doped Polymer Optical Fiber

Abstract

We report on fabrication of a rhodamine-6G-gold-nanoparticle doped polymer optical fiber. The gold nanoparticle is synthesized directly into the monomer solution of the polymer using laser ablation synthesis in liquid. The size of the particle is found from the transmission electron microscopy. Rhodamine-6G is then mixed with the nanoparticle-monomer solution and optical characterization of the solution is investigated. It is found that there is a pronounced quenching of fluorescence of rhodamine 6G due to fluorescence resonance energy transfer. The monomer solution containing rhodamine 6G and gold nanoparticles is now made into a cylindrical rod and drawn into a polymer optical fiber. Further, the photostability is calculated with respect to the pure dye doped polymer optical fiber.

Optical Characterization of Doped Thermoplastic and Thermosetting Polymer-Optical-Fibers

“…The manufacturing technology of POFs is cheaper and simpler than that of glass fibers, and their mechanical strength is also higher. Their lower manufacturing temperatures make it possible to dope the fiber core with an ample variety of active materials like organic dyes, conjugated polymers, rare-earth ions, noble-metal nanoparticles, or quantum dots [ 3 , 4 , 5 ]. High optical gains can be achieved in remarkably short fiber lengths by doping POFs with organic dyes having high absorption and emission cross sections.…”
