摘要：
Electrospun, emission color-tunable nanofibrous sheets were fabricated by multinozzle electrospinning equipped with a secondary electrode for the preparation of white-emissive sheets under a single excitation source, manipulating energy transfer between dyes. By control of the concentration of commercially available red, green, and blue dyes in the matrix polymer [poly(methyl methacrylate)], emission color tuning can be easily accomplished because each dye is located in spatially separated fibers to maintain enough distance to prevent or suppress energy transfer, allowing white-light emission. The application of dye separation for the whitelight emission upon excitation with a blue light-emitting-diode lamp is demonstrated, indicative of its potential application for the easy and facile tuning of fluorescence color toward flexible illumination.
