Carbon dots (C-dots) are nanoparticles composed of carbon with diameters below 10 nm. They were accidentally discovered in 2004 by Xu, et al1 when researching methods to purify carbon nanotubes. Since their discovery they have received much attention from the Materials Science community as a potential alternative to semiconductor quantum dots, especially in biological applications due to their low toxicity. Some of their applications include photocatalysis, solar cells, bioimaging and drug delivery.

As photoluminescence (PL) research evolves, so does the demand for sensitive instrumentation to measure increasingly weak PL signals. Besides photon-counting detectors and monochromators with good stray light rejection, the source used to excite the sample is a key component to consider when designing an experiment.

Liquid scintillator detectors are widely utilised in neutrino and astroparticle detection experiments. One liquid scintillator that is increasingly being used in large scale detection experiments is linear alkylbenzene (LAB). LAB is an attractive scintillator due to its low cost, high flash point and low toxicity; making it easier to handle than previously used toxic and flammable organic solvents. LAB is commonly used together with the fluor 2,5-diphenyloxazole (PPO) which increases luminescence yield and shifts the luminescence to longer wavelengths.In this application note the properties of the liquid scintillator system LAB/PPO are investigated using time-resolved X-ray excited luminescence spectroscopy with the FLS1000 and XS1 X-ray Sample Chamber.

Forensic investigations often study extremely small samples which may need analysed by multiple techniques. Confocal Raman and Photoluminescence (PL) Microscopy are well-suited techniques for dealing with such samples. This application note details how Raman and PL microscopy can be used as an analysis tool in any forensic laboratory.
