## Description

- description: "Lead halide perovskite quantum dots (QDs) have emerged as promising
    scintillator materials, however, their emission behavior under ionizing radiation
    in solution remains insufficiently characterized. In this study, we investigated
    the radiation-induced luminescence of commercially sourced colloidal lead halide
    perovskite QDs in toluene (CsPbCl2Br, CsPbBr3 and FAPbBr3) using pulse radiolysis
    with high-energy electron beams.\r\nThe radioluminescence spectra closely coincides
    with the steady-state photoluminescence spectra, indicating that the same band-edge
    emissive states are populated under both optical and ionizing radiation excitation.
    Despite significant difference in photoluminescence quantum yields (0.44-0.83),
    the relative radioluminescence intensities show no direct correlation with photoluminescence
    efficiencies. This result is consistent with the contribution of solution-phase
    radiation processes, in which excitation is generated not only within the nanocrystals
    but also through radiolytically produced solvent-derived species. In addition,
    the emission spectrum, linewidths and intensities remain unchanged after gamma-ray
    irradiation up to 17 Gy, indicating that these colloidal QDs retain their photophysical
    characteristics within this dose range.\r\nThese results provide an experimental
    basis for distinguishing optical excitation from ionizing-radiation-induced excitation
    in colloidal perovskite QDs and demonstrate the utility of pulse radiolysis for
    evaluating radioluminescence processes in luminescent nanomaterials. Rather than
    introducing a new scintillator composition, this study provides a controlled experimental
    comparison of optical and ionizing-radiation excitation in a solution-phase perovskite
    QD platform."
