Quantum dots are semiconductor nanocrystals that emit light over a short range of wavelengths. Electronics manufacturers want to use the materials to develop light-emitting diodes (LEDs) for lighting ...

Chemical engineers report an easy, low-cost method to make carbon nanoparticles that glow pure white (Ind. Eng. Chem. Res. 2014, DOI: 10.1021/ie500602n). The team used the particles, known as carbon ...

Warren Chan helped invent a research field and then watched it nearly die. The chemist and biomedical engineer at the University of Toronto specializes in quantum dots, tiny semiconductor particles ...

STOCKHOLM — Three U.S.-based scientists won the Nobel Prize in chemistry Wednesday for their work on quantum dots — particles just a few atoms in diameter that can release very bright colored light ...
