Tin activated hafnia phosphor composition and X-ray intensifying screen. |
| 摘要 |
<p>A phosphor composition which consists essentially of oxygen and a combination of elements satisfying the relationship: [(Hf1-zZrz):xSn yTi wherein x is in the range of from 0.0002 to 0.05, y is in the range of from 0 to 0.005, and z is in the range of from 0 to 0.5. The composition is used in an intensifying screen for producing a latent image in a silver halide radiographic element when imagewise exposed to X-radiation. <IMAGE></p> |
