b) positioning said substrate fixture in a vapor deposition chamber having a vapor
generator, said substrate fixture being positioned at an oblique angle to said vapor
generator;
c) introducing phosphor constituents into said vapor generator capable of forming a
vapor of said phosphor constituents;
d) placing said chamber under an inert atmosphere;
e) activating said vapor generator to form an ingot pool of said phosphor constituents
and thereby generate said vapor of said phosphor constituents;
f) directing said vapor of said phosphor constituents towards said substrate fixture;
g) maintaining a constant height of said ingot pool of said phosphor constituents in said
vapor generator; and
h) rotating said substrate fixture for a time sufficient to effect deposition of a phosphor
complex on said imaging screen substrate to thereby form said anisotropic, auto-
collimating imaging screen.
