The chitosan and organic Eu2+ nanophosphors based photochromic emulsion have been prepared by wet chemical method and coated on glass fiber by solvent evaporation technique. For this purpose, glass fibers were dipped in acetic acid solution; containing dissolved chitosan and Eu2+ nanophosphors. The coated fibers were characterized by FE-SEM, XRD, FT-IR and UV-PL. The coated fibers under UV irradiation showed broad-band absorption from 220-400nm wavelength; and quick photo-emissive response at 450nm wavelength, in pure blue region with high degree of reproducibility. The results indicate that, composite could endow glass fibers with excellent fluorescent properties. These glass fibers composite with remarkable photosensitivity found potential application as in smart and intelligent functional textiles.
