Phosphorus composition and principal X-ray intensifier screen emitting in the spectral range of silver halide sensitivity.

摘要

A phosphor composition is disclosed containing a titanium activated hafnium zirconium germanate phosphor which emits electromagnetic radiation principally in the spectral region to which silver halide exhibits native sensitivity. To maximize the intensity of emission the ratio of host metals satisfies the relationship: MATH where D is the combined sum of zirconium and hafnium and x is 0.25 to -0.70. An X-ray intensifying screen is disclosed containing the phosphor composition. IMAGE
