Photoluminescence Spectroscopy of Carbon Dots

In this whitepaper Edinburgh Instruments characterise an inhomogeneous distribution of carbon dots produced by thermal treatment of milk. In this case carbonisation is achieved by simply heating up milk in air to 220 °C for 2 hours, and the photoluminescence spectra and lifetimes of the resulting C-dots are studied in an FLS1000 Photoluminescence Spectrometer.
