Title: Eu(III)-coupled luminescent multi-walled carbon nanotubes in surfactant solutions
Abstract: A carbon nanotube/inorganic hybrid material has been fabricated by Eu(III) complexes onto multi-walled carbon nanotubes (MWCNTs). coupling has been verified by X-ray photoelectron (XPS) measurement where a clear signal from Eu3d has been When sonicated in hexaethylene glycol monododecyl ether or sodium dodecyl sulfate (SOS) aqueous solutions, the with Eu-complex attached (denoted as Eu-MWCNTs hereafter) can be UV-vis measurements on a dilute dispersion of Eu-MWCNTs in aqueous solution reveal the characteristic absorption from Eu(III) which gives further proof of the successful coupling. The luminescent properties of Eu-MWCNTs allow them to be observed under a fluorescence microscope. Interestingly, it is found Eu-MWCNTs can undergo continuous movements in C(12)E(6) or SDS solutions. When Eu-MWCNTs are incorporated into the lyotropic crystal phase formed by C(12)E(6) (above 40\% by weight), movements have been hindered. Small angle X-ray scattering showed that Eu-MWCNTs are ordered in the lyotropic liquid Fluorescence microscopy observations reveal that the properties of the Eu-MWCNTs have not been affected by the crystalline surfactant matrix.
