The present invention relates to a scintillator for the input screen of a tube for intensifying radiological images, the needles (2) of cesium iodide of the scintillator being coated with a refractory, transparent or reflecting material (5) close to or less than that of cesium iodide. Various methods can be used for the coating, such as chemical vapor deposition, activated by thermal excitation, plasma excitation, or photonic excitation; or such as the diffusion deposit of a colloidal solution; or such as the polymerization of a polymer resin. After the coating, the heat treatment is carried out which ensures the luminescence of the screen. |
