| More Details: | Scintillators, which convert high-energy radiation into detectable photons, play a crucial role in medical imaging and security applications. The enhancement of scintillator performance through nanophotonics and nanoplasmonics, specifically using the Purcell effect, has shown promise but has so far been limited to ultrathin scintillator films due to the localized nature of this effect. In this study, we present a method to extend nanoplasmonic scintillators to the bulk regime. By integrating 100-nm-size plasmonic spheroid and cuboid nanoparticles with perovskite scintillator nanocrystals, we enable nanoplasmonic scintillators to function effectively within bulk-scale devices. We experimentally demonstrate power and decay rate enhancements of up to (3.20 $\pm$ 0.20) and (4.20 $\pm$ 0.31) fold for plasmonic spheroid and cuboid nanoparticles, respectively, in a 5-mm thick CsPbBr$_3$ nanocrystal-polymer scintillator at RT. Theoretical modeling further predicts similar enhancements of up to (2.63 $\pm$ 0.79) and (5.62 $\pm$ 1.71) fold for the same nanoparticle shapes and dimensions. These findings provide a viable pathway for using nanoplasmonics to enhance bulk scintillator devices, advancing radiation detection technology.
