Show me the money ! A printable ink with three modes of optical authentication could be used to combat counterfeiting. In their Communication on page 7231 ff., H. Lin and co‐workers describe a carbon dot composite fixed in a PVA matrix with three modes of simultaneous emission; Chinese dragon boaters in various shades of blue depict photoluminescence (PL), up‐conversion PL (UCPL), and room temperature phosphorescence (RTP) emission by carbon dots.
