Coal yields plenty of graphene quantum dots

December 7th, 2013

The prospect of turning coal into fluorescent particles may sound too good to be true, but the possibility exists, thanks to scientists at Rice University.

From coal, cheap quantum dots in one step
Rice researchers have discovered how to reduce three kinds of coal into graphene quantum dots that could be used for medical imaging as well as sensing, electronic, and photovoltaic applications. James Tour, the T.T. and W.F. Chao Chair in Chemistry and professor of mechanical engineering and materials science and of computer science, and Angel Martí, assistant professor of chemistry, bioengineering, materials science and nanoengineering, are quoted.
