Abstract

L'invention concerne un matériau scintillateur comprenant un silicate de terre rare dopé au cérium caractérisé en ce que sa densité optique à la longueur d'onde 357 nm est inférieure à sa densité optique à 280 nm. Ce matériau présente une luminescence retardée généralement inférieure à 200 ppm après 100 ms rapportés à l'intensité mesurée pendant une irradiation sous rayons X. Il est de préférence co-dopé. Il peut être obtenu par un recuit oxydant. Il est particulièrement adapté à être intégré dans un détecteur de particules ionisantes pouvant servir dans un appareil d'imagerie médicale.
