Size-Dependent Multiexciton Dynamics Governs Scintillation From Perovskite Quantum Dots.

ABSTRACT: The recent emergence of quantum-confined nanomaterials in the field of radiation detection, in particular lead halide perovskite nanocrystals, offers scalability and performance advantages over conventional materials. This development raises fundamental questions about the mechanism of scintillation itself at the nanoscale and the role of particle size, arguably the most defining parameter of quantum dots. Understanding this is crucial for the design and optimization of future nanotechnology scintillators. In this work, these open questions are addressed by theoretically and experimentally studying the size-dependent scintillation of CsPbBr₃ nanocrystals using a combination of Monte Carlo simulations, spectroscopic, and radiometric techniques. The results show that the simultane
