Title: Process for manufacturing an auto-collimating scintillator and product produced thereby

There is described a process for the vapor deposition of a scintillator phosphor composition with concomitant shadowing wherein the substrate to be processed is rotated through an arc relative to a vapor source of the scintillator phosphor composition whereby shadowing introduces voided gaps or interstices between columns as a result of the preferential components receiving more coating flux, particularly in the presence of oblique flux. 8 figs.
