Colorimetric and fluorescent nanofibrous film as a chemosensor for Hg~(2+) in aqueous solution prepared by electrospinning and host-guest interaction

摘要

A fluorescent sensing film for Hg~(2+) ions was fabricated by host-guest interaction and electrospinning. When the nanofibrous film was put into a solution of Hg~(2+) ions, it gave rise to orange fluorescence, causing a clear color change from white to pink-red.
