Synthesis and surface functionalization of rare earth nanoparticle and multiwalled carbon nanotube.

We report a novel method to prepare NaYF4: Yb, Er/ Multiwalled Carbon Nanotube (MWCNT) nanocomposites. Hydrothermal treatment at 180⁰C was employed to coat the up-conversion NaYF4: Yb, Er around the MWCNT. When pristine multiwalled carbon nanotubes are used, rod-like nanoparticles of NaYF4: Yb, Er a...
