Abstract[English]
An X-ray imagining film (610) that transforms X-ray radiation (614) into visible light (612) by scintillating, includes a substrate (604) and a nanocomposite (100) formed on the substrate (604). The nanocomposite (100) includes perovskite nanosheets (110) and plural organic chromophores (120) that interact with the perovskite nanosheets (110) through F-Pb bonds. The perovskite nanosheets (110) are selected to absorb the X-ray radiation (614) and emit first light centered on 510 nm, and the plural organic chromophores (120) are selected to absorb second light between 400 and 600 nm, with a peak at 510 nm, and emit the visible light (612) in 500 to 800 nm range.[French]
Un film d'imagerie par rayons X (610), qui transforme un rayonnement de rayons X (614) en lumière visible (612) par scintillation, comprend un substrat (604) et un nanocomposite (100) formé sur le substrat (604). Le nanocomposite comprend des nanofeuilles de pérovskite (110) et plusieurs chromophores organiques (120) qui interagissent avec les nanofeuilles de pérovskite (110) par l'intermédiaire de liaisons F-Pb. Les nanofeuilles de pérovskite (110) sont sélectionnées pour absorber le rayonnement des rayons X (614) et émettre une première lumière centrée sur 510 nm, et la pluralité de chromophores organiques (120) sont sélectionnés pour absorber une seconde lumière entre 400 et 600 nm, avec un pic à 510 nm, et émettre la lumière visible (612) dans une plage de 500 à 800 nm.
