Abstract
The present invention provides an input screen scintillator for a radiological image intensifier tube in which the cesium iodide needles of the scintillator are coated with a refractory, transparent of reflecting, material having an optical index close to or less than that of the cesium iodide. Different methods may be used for coating, such as chemical vapor phase deposition, activated by thermal excitation, plasma excitation or photonic excitation; or such as diffusion deposition of a colloidal solution; or such as polymerization of a polymer resin. After coating, is realized the heat treatment which ensures the luminescence of the screen.
