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...

We report a novel method to prepare NaYF4: Yb, Er/ Multiwalled Carbon Nanotube (MWCNT) nanocomposites.

When pristine multiwalled carbon nanotubes are used, rod-like nanoparticles of NaYF4: Yb, Er are found to be coated on p-MWCNT. The particle size is varied from 25-50nm and display a distinct boundaries with MWCNT.

The morphology of the NaYF4: Yb, Er coating, coating thickness and the up-conversion efficiency is highly depends on the synthesis environment pH and the condition of the MWCNT. |
