摘要：<p>An X-ray intensifying screen with improved resolution at a constant coating weight and speed comprises a phosphor-binder layer coated on a support, wherein the phosphor comprises a rare earth tantalate phosphor in which 5-80% has a tabular morphology with an average aspect ratio of about 2:1 and the remainder of the phosphor has a polyhedral morphology.</p>
