[flash /ceramictechtoday/wp-content/video/wrapped_nanotube.flv mode=1 f={image=/ceramictechtoday/wp-content/video/wrapped_nanotube.jpg}] A team from UConn’s Nanomaterials Optoelectronics Lab at the Institute of Materials Science has discovered a nifty way to increase the photoluminescence of single-walled carbon nanotubes by wrapping the tubes with a sleeve made from a Vitamin B2 analog. The wrapping prevents defects caused by oxygen and renders them much more…
