Unified nanophotonic scintillation model and Geant4 integration

Develop and validate a unified theoretical and computational model of nanophotonic scintillators that captures both energy loss by high-energy particles and light emission in nanostructured optical environments, and integrate this model into the Geant4 toolkit to enable accurate simulation of quantum-dot–based chromatic calorimetry and related detector designs.

Background

The paper’s proposed chromatic calorimeter relies on quantum-dot emission shaping within scintillators and uses Geant4 for simulation. The authors note that current Geant4 lacks native support for nanophotonic scintillation and quantum-dot physics, and they highlight the need for a comprehensive model bridging particle energy deposition and nanophotonic emission processes.

They reference an initial theoretical framework (Roques‑Carmes et al.) as a foundation but emphasize that practical validation and full integration into Geant4 remain necessary milestones to move from proof-of-concept simulations to experimentally reliable modeling.
