    摘要: The present invention provides a digital x-ray radiographic imaging system. The system is based on a photoconductive detector and an electro-optic light modulator, where the photoconductive detector layer absorbs x-rays that have passed through an object to form an exposure of the object. The absorbed x-rays create a static optical image, which is stored in the electro-optic light modulator, allowing the capture of the optical image to continue over longer time. The optical image is digitized using a scanning system and an external light source. The image is then processed and stored by a computer. After the optical image is recorded, an erasing mechanism is used to reset the system before a new exposure is made.

    摘要: The present invention provides thioaluminate phosphor compounds BaAl2S4 and BaAl4S7 with novel crystal structures that have higher luminosity and improved colour coordinates. The invention is also directed to rare earth element activated barium thioaluminate phosphor films comprising a phosphor compound having a novel crystal lattice structure that increases the electroluminescent light emission from the film. The phosphor films are for use in electroluminescent displays and in particular, thick film dielectric electroluminescent displays.
