Abstract

A scintillator plate includes a substrate, a buffer layer, a scintillator layer arranged on the buffer layer, and a protective layer. The buffer layer and/or the protective layer is colored. A method for the production of the scintillator plate is also described.

First claim

The invention claimed is:

1. A method for manufacturing a scintillator plate, the method comprising:
providing a substrate;
applying a buffer layer to the substrate;
applying a scintillator layer to the substrate;
applying a protective layer to the scintillator layer;

wherein the buffer layer, the protective layer, or both the buffer layer and the protective layer are colored by tempering following the application thereof, wherein the tempering is implemented in a temperature range from 190° C. to 240° C. in an oxygen-containing atmosphere.

2. The method of claim 1 , wherein the buffer layer, the protective layer, or both the buffer layer and the protective layer are made of one of parylene C, parylene N and parylene D.

3. The method of claim 2 , wherein the scintillator layer forms microstructures such that interstices form between the microstructures essentially perpendicularly to the surface of the scintillator plate toward the substrate, wherein the protective layer penetrates into the interstices during application.

4. The method of claim 1 , wherein the scintillator layer forms microstructures such that interstices form between the microstructures essentially perpendicularly to the surface of the scintillator plate toward the substrate, wherein the protective layer penetrates into the interstices during application.

5. The method of claim 4 , wherein the scintillator layer comprises caesium iodide.

6. The method of claim 1 , wherein the scintillator layer forms microstructures such that interstices form between the microstructures essentially perpendicularly to the surface of the scintillator plate toward the substrate, wherein the protective layer penetrates into the interstices during application.
