Abstract
In the exemplary embodiments, the luminescent layer is applied to a carrier exhibiting a grid which is applied in the manner known per se in applying photo grids. Thereby, however, it is disadvantageous that the grid interstices exhibit only a small depth, so that the grid structure disappears as the luminescent layer is applied with increasing thickness. In order to avoid this disadvantage, the disclosure provides that the carrier also be etched after application of the grid, so that the grid interstices receive the shape of enlarged recesses of greater depth. The luminescent layer applied to this grid then retains the grid-like interruptions even given a greater thickness. An inventive luminescent screen receives improved image transmission properties and is particularly suited for employment as an X-ray (image intensifier) luminescent screen in medical X-ray diagnostics.
