Separation and Diameter-Sorting of Empty (End-Capped) and Water-Filled (Open) Carbon Nanotubes by Density Gradient Ultracentrifugation

Sorting by spinning: Empty (end‐capped) and water‐filled (open) carbon nanotubes, which coexist in aqueous solutions, can be separated by density gradient ultracentrifugation (see picture), and the empty tubes allow enhanced diameter sorting. The isolated empty nanotubes possess narrower electronic...

Summary:Sorting by spinning: Empty (end‐capped) and water‐filled (open) carbon nanotubes, which coexist in aqueous solutions, can be separated by density gradient ultracentrifugation (see picture), and the empty tubes allow enhanced diameter sorting. The isolated empty nanotubes possess narrower electronic and vibrational transitions and enhanced quantum efficiences compared to the water‐filled nanotubes.
