Abstract
A cathodoluminescent mosaic screen on a light-transparent substrate wherein the light-emitting components of the screen are implemented as light-guiding single-crystalline columns. A method for preparation of the screen by vapor deposition of the luminescent material onto the substrate coated by a localized liquid phase has been proposed.
Claims12
A method of preparing luminescent screens, comprising:
- providing a substrate having columns of a single-crystalline material, the single-crystalline material having a predetermined crystallization temperature;
- depositing an intermediate material on the substrate, wherein the intermediate material forms liquid at the crystallization temperature of the single-crystalline material;
- and depositing a luminescent material on the substrate, wherein the luminescent material is different from the intermediate material.
