X-ray intensifying screen and phosphor composition.
摘要
<p>An intensifying screen is disclosed containing a phosphor composition comprised of monoclinic crystals of a titanium activated hafnia phosphor host containing indium ions or indium ions in combination with neodymium ions. Indium increases speed while reducing afterglow while the further addition of neodymium allows afterglow to be eliminated. A phosphor composition in which zirconia is at least partially substituted for hafnia is also disclosed.</p>
