PROTECTIVE OVERLAYER FOR PHOSPHOR IMAGING SCREEN

摘要

A stimulable phosphor having a plasma-deposited protective coating comprising a substantially continuous, protective coating which conforms substantially to the surface of the stimulable phosphor. In a preferred embodiment, the coating has a thickness of between about 0.10 and about 1.0 .mu.m, and provides a thinner coating having greater sensitivity to radiation emitted from weak radioactive labels than conventional screen protective coatings, but with effective protection from moisture and physical damage.
