X-RAY PHOTOCONDUCTIVE NANOCOMPOSITES

The successful development of digital radiography depends, to a large extent, on the availability of suitable x-ray photoconductors. The x-r ay photoconductive nanocomposites reported here combine the advantages of both inorganic and organic compounds. An inorganic compound was fi nely dispersed in an organic polymer. The inorganic compound, with its large x-ray absorption efficiency, functioned as the x-ray absorber, and the polymer provided good dielectric properties and ease of thin-f ilm preparation. The preparation procedures and the x-ray photoconduct ive properties of a specific example, a 50 percent by weight nanocompo site of bismuth triiodide and nylon-11, are discussed In detail.
