Abstract

La présente invention concerne un détecteur de scintillation comprenant des nanoparticules d'un composant de scintillation intégré dans une matrice en plastique. Les nanoparticules peuvent être réalisées à partir d'oxydes métalliques, d'oxyhalogénures métalliques, d'halogénures métalliques, d'oxysulfures métalliques. La présente invention concerne également des procédés pour préparer les nanoparticules. Les particules peuvent être revêtues avec des composants organiques ou des polymères avant d'être incorporées dans la matrice en plastique. Une technique pour faire correspondre l'indice de réfraction de la matrice en plastique avec les nanoparticules en incorporant des nanoparticules de dioxyde de titane est également fournie. Le scintillateur peut être couplé à un ou à plusieurs détecteurs optiques afin de former un système de détection de scintillation. Le système de détection de scintillation peut être adapté pour être utilisé dans des dispositifs d'imagerie par rayonnement ou par rayons X, tels que les dispositifs d'imagerie à rayons X, de mammographie, CT, PET ou SPECT, ou pour être utilisé dans des détecteurs de sécurité de radiation ou des détecteurs de radiation souterraine.
