The Takeaway
Researchers found that 'carbon dots' synthesized from common household materials can act as light-emitting sensors for subatomic particles when dissolved in water. This discovery could replace expensive, hazardous industrial chemicals with eco-friendly DIY materials for massive physics experiments.
From the abstract
Liquid scintillators underpin a wide range of radiation detectors, including those used in neutrino physics, but typically rely on organic fluors dissolved in hazardous and costly solvents. Here, we show that carbon dots - nanoscale fluorescent carbon materials - synthesised from simple household ingredients using a microwave can function as water-based liquid scintillators. These carbon dots dispersed in water produce light yields up to 70 +/- 20 photons per MeV and enable the detection of atmo
