Using a simple low-temperature chemical-solution method, multi-walled carbon nanotubes (MWCNTs) coated with crystalline multi-walled europium oxide nanotubes have been successfully synthesized (see Figure). The studies conducted show that such MWCNTs provide an opportunity for synthesising various rare earth oxide nanotubes, including non-layered structure compounds, potentially useful for nanoscale optoelectronic devices.
