scintillation

With each technological shift, the scintillation of new possibilities meets the tug of obsolescence.

Additionally, organic plastic scintillators suffer from low scintillation yields and low particle radiation tolerances due to their low electron density, which hampers their single-proton detection sensitivity.

The research team has put forward and substantiated a novel theory regarding the scintillation mechanisms induced by protons in CsPbBr3 nanocrystals.

They have verified that proton-induced scintillation primarily arises from the population of the biexcitonic state in CsPbBr3 nanocrystals, facilitated by the process of proton-induced upconversion and impact ionisation.

This finding represents a significant contribution to the understanding of proton scintillation in perovskite nanocrystals.
