Fabrication and structural characterization of the photochromic fiber. (IMAGE)
Caption
a Photograph of the industrial-scale fabrication line of the photochromic fiber. The scale bar corresponds to 0.5 m. b Schematic illustration of the fabrication of the photochromic fiber. The inset shows a photograph of the fabricated and illuminated photochromic fiber. The scale bar corresponds to 10 cm. c Comparison of the luminescence attenuation in the transmission direction between this work and the commercial product (light diffusing fiber). d-f Cross-sectional optical micrograph of three types of photochromic fiber, showing a different number of cores in the fiber, d for single-core red color. e for dual-core red and green colors, and f for tri-core red, green, and blue colors. The scale bar in each case corresponds to 200 μm. g-i Photographs of the photochromic fiber under radial observation. g for red color at 0°, 90°, 180°, and 270° angles, h for dual-core red and green colors at 0°, 90°, 180°, and 270° angles, and i for tri-core red, green, and blue colors at 0°, 90°, 180°, and 270° angles. The scale bar in each case corresponds to 500 μm.
