Carbon dots fluoresce their way through the rainbow as liquids change
Phys.org ·
Fluorescent materials usually emit a single consistent color. They are typically made from dyes or metallic components. In contrast, researchers reporting in ACS Central Science have created carbon dots that can fluoresce in a range of colors under UV light, depending on the concentration and the liquid they're in. The team incorporated the new carbon dots into plastic decorations and used them to create a data encryption system.
