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.

The fastest imaging technique on the market. Combining high-speed ASOPS and efficient THz generation antenna allows for spectroscopic imaging at 10 kpixels / second acquisition speed, with an excellent signal to noise ratio. Being able to measure the phase and amplitude information at this high speed is unmatched by any other device on the market.

With an explosion of scientific interest in graphene based material for its incredible electronic, optical, and physical properties; it became clear that we needed to develop a cost effective instrument that could be used for quality determination as well as characterization

Confocal Raman imaging and related techniques continue to increase in popularity. This whitepaper describes five key factors to consider when evaluating instrumentation: speed, sensitivity, resolution, modularity and upgradeability, and combinability.

In this whitepaper PhOLED are investigated using an FS5 Spectrofluorometer with electroluminescence accessory. Spectrum and chromaticity coordinates of the PhOLED emission are measured and triplet lifetime determined using time-resolved spectroscopy.
