What is it about?
Scintillators detect ionising radiation by converting energy deposited in them to photons. They are omnipresent in large-scale technical and commercial applications around us. For example, they are found in many branches of physics, security scanners, and medical applications such as nuclear imaging for cancer diagnostics.

Why is it important?
An ideal scintillator emits a maximum number of scintillation photons per unit energy deposited, has a high absorption coefficient for gamma quanta, and exhibits a narrow timing profile for its scintillation photons. Brighter and faster scintillators facilitate better timing resolution, which is crucial for measuring the time of the initial particle or radiation interaction with high precision. At present, the dominant limitation of modern scintillators is their timing resolution. This limits the imaging resolution of PET scanners that are used for medical cancer imaging.
