True photoluminescence spectra revealed in electrospun light-emitting single nanofibers
Abstract
We demonstrate for the first time that re-absorption and scatterings of photoluminescence (PL) significantly occur among electrospun light-emitting nanofibers. Electrospun nanofibers composed of a blend of poly[2-methoxy-5-(2′-ethyl-hexyloxy)-1,4-phenylenevinylene] and poly(ethylene oxide) with and without LiCF3SO3 were prepared in controlled numbers. Different numbers of fibers showed different
