ABSTRACT:
This invention relates to fluorescent photosensitive vitroceramics and the process for the production thereof. The fluorescent photosensitive vitroceramics according to the present invention employ fluorosilicate glass compositions including various photosensitizing metals and rare earths which impart photosensitive properties and fluorescent properties to the vitroceramic. After irradiation, the photosensitive agents control the precipitation of fine fluoride crystals which also contain rare earth ions. These rare earth ions can be made to fluoresce in a controlled manner. The inventive fluorescent photosensitive vitroceramics can be used in photographic applications, florescent displays and computer memories.
