Abstract

A method is disclosed, in at least one embodiment, for producing a scintillator for a radiation detector, in which the scintillator is produced in layers by depositing a scintillator material using a PVD process. By using a PVD process, owing to lower process temperatures of less than 300° C., it is possible to produce scintillators with decay times of less than 1.1 ns over large surfaces. In this way, the prerequisites for quantitative and energy-selective detection of individual radiation quanta can be satisfied even with fluxes of more than 108 X-ray quanta/mm2*s. At least one embodiment of the invention also relates to a scintillator produced by such a method.
