Abstract

Rare earth complex hybrid ionogel is an emerging functional material that can combine the unique properties of ionic liquids with the luminescent properties of rare earth elements. Here, we report a synthesis of novel luminescent ionogels via a simple and convenient method of basing on the thermal curing method. The luminescent ionogels were prepared by confining the ionic liquid within a cross-linked polymer networks which the Eu3+/Tb3+ complex covalently bonded onto. The ionogel reported here shows outstanding luminescence properties that originated from the corresponding rare earth complexes: broad excitation spectra, line-like emission spectra, long luminescence lifetimes and so on..
