Nanophotonics for next-generation X-ray scintillators

Abstract

This study explores the use of one-dimensional photonic crystal (PhC) cavities to enhance the optical performance of X-ray scintillators. By simulating various material systems in MATLAB, we evaluate the impact of PhC structures on emission spectra and timing characteristics through the Purcell effect. Results show that PhC integration can improve spectral intensity and photon extraction efficiency, though it may introduce delayed emission onset depending on material and structural parameters. These findings provide guidance for designing advanced scintillator systems for imaging and detection applications.
