Quantum dots fluoresce in a range of colors under UV light in the lab of University of Rochester Professor of Chemistry Todd D. Krauss in Hutchison Hall December 4, 2017. Krauss and his graduate student, Leah Frenette, have described the underlying mechanisms involved in producing quantum dots, including their discovery that the safer, more controllable compounds now used to produce a widely used class of quantum dots decompose during the process into the same highly toxic compounds used in their initial production 30 years ago. // photo by J.
