Towards a second generation of metascintillators using the Purcell effect
arxiv(2024)
摘要
This study focuses on advancing metascintillators to break the 100 ps barrier
and approach the 10 ps target. We exploit nanophotonic features, specifically
the Purcell effect, to shape and enhance the scintillation properties of the
first-generation metascintillator. We demonstrate that a faster emission is
achievable along with a more efficient conversion efficiency. This results in a
coincidence time resolution improved by a factor of 1.6, crucial for TOF-PET
applications.
