摘要：Ionogel is an emerging hybrid material which is usually constructed by confined an ionic liquid into some special matrices, and it is expected to have great potential applications in the field of electrolyte materials, opticalelectric materials and so on. Here, a terbium complex covalently modified graphene was introduced into the 1-butyl-3-methylimidazolium bis[(trifluoromethyl)sulfonyl]imide ionic liquid based ionogel matrix. The resulted material is a kind of novel photoluminescent hybrid material which has a transparent appearance and shows strong green under the UV light. The photoluminescent properties of the ionogel has been measured in details, revealing a broad excitation spectra, line-like emission spectra and long luminescence lifetimes which make it great potential applications in the preparation of optical-electric devices, together with the intrinsic conductive property of the embedded ionic liquid.
