title: Nanocrystal hybridized scintillators for enhanced detection and imaging on Si platforms in UV.
abstract: We report on the conception, design, fabrication, experimental characterization, and theoretical analysis of nanocrystal scintillators hybridized on Si detectors and CCDs for enhanced detection and imaging in UV. Integrating luminescent CdSe/ZnS core-shell nanocrystals (NCs of 3.2 and 5.2 nm in diameter with 5% size distribution) to efficiently convert incident UV radiation to visible emission, we demonstrate hybrid NC-Si photodetectors that exhibit significantly improved responsivity between 200-240nm, experimentally with a two orders of magnitude peak enhancement and theoretically with a three orders of magnitude peak enhancement. Such nanocrystal based scintillators hold great promise in UV detection and imaging on Si platforms.
