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.
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.
