Buckybulbs

MOLECULAR light bulbs designed by chemists in California could be used to produce glowing walls that change colour at the turn of a dial. Certain types of buckyballs—molecular cages made of carbon atoms—fluoresce when stimulated by light. Fred Wudl of the University of California at Los Angeles and his colleagues blended these buckyballs with chemicals that transport and capture electrons. As the team report in a forthcoming issue of the Journal of the American Chemical Society, a thin layer of the mix glowed white when they applied a current to it. Although the first “buckybulbs” are too dim to have practical applications, Wudl says, they could eventually be incorporated into flat-panel displays,
