摘要： A phosphor composition is disclosed comprised of phosphor crystals which consist essentially of oxygen and a combination of metals satisfying the relationship:
Li₂Hf 1-x-y-z Zr z Sn y Ti x L w
where
L is at least one rare earth;
w+x+y collectively are 0 to 0.2; and
z is up to 0.2.
The composition has utility in an intensifying screen for producing a latent image in a silver halide radiographic element when imagewise exposed to X-radiation.摘要翻译： 公开了一种荧光体组合物，其由基本上由氧和满足以下关系的金属的组合构成的荧光体晶体组成：Li2Hf1-x-y-zZrzSnyTixLw其中L是至少一种稀土; w + x + y共同为0〜0.2; z高达0.2。 当成像暴露于X射线时，该组合物在增强屏幕中用于在卤化银放射照相元件中产生潜像。
