Abstract
Disclosed is a improvement in the fabrication of a scintillator, notably for the input screen of an X-ray image intensifier tube. According to the disclosure, the substrate on which a layer of scintillating material such as cesium iodide deposited in is made to grow is subjected to a treatment resulting in the formation of an alveolate structure or surface state, the consequence of which is the formation of thinner needles. The reduction of the mean diameter of the needles results in a improvement of the resolution of the device.
