Preparation and Modification of Fluorescent PAN Nanosphere and Its Application in White Light Phosphors

A kind of monodispersed and flower-like polyacrylonitrile (PAN) nanosphere, one of the most popular polymers without traditional fluorophore, has been successfully prepared by one-step method. Pristine PAN nanosphere exhibits fluorescent emission at 400 nm. Remarkably, after hydrolysis reaction of P...

Summary:A kind of monodispersed and flower-like polyacrylonitrile (PAN) nanosphere, one of the most popular polymers without traditional fluorophore, has been successfully prepared by one-step method. Pristine PAN nanosphere exhibits fluorescent emission at 400 nm. Remarkably, after hydrolysis reaction of PAN nanosphere in alkaline aqueous solution, the maximum emission wavelength red-shifted from 400 nm to 465 nm. Furthermore, according to fluorescent lifetime decay and other data, we can hypothesize that the hydrolysed PAN sample contains different emissive species from pristine PAN nanosphere. Based on above results, a novel kind of white light phosphors is fabricated when introduced rhodamine 6G onto the rugged surface of flower-like PAN nanosphere. Our work suggests that the as-prepared PAN nanosphere exhibits great potential application in the field of optical material.
