摘要

The objective of the program was to synthesize a cathodoluminescent phosphor with greatly increased ultraviolet emission efficiency in the spectral region between 350 and 400 nanometers for the purpose of writing on photochromic or Kalvar media. Twenty-nine phosphor compositions were studied in at least a preliminary manner and several of these more extensively. Relative to P-16 powder, sprayed films of calcium magnesium silicate: cerium showed an average writing efficiency on Kalvar nearly ten times greater in a demountable system. Another sprayed film phosphor, BaZn1.9Mg0.1Si2O7:Pb with spectral peak at about 300 nm was shown to be about ten times more efficient than P-16 powder in writing on a spiropyran photochromic film in a demountable system. Demonstration cathode ray tubes were fabricated with the sprayed phosphor films, BaSi2O5:Pb, calcium magnesium silicate: cerium, and Zn2SiO4:Ti, and settled powder P-16 screens incorporated. Phosphors in cathode ray tubes generally were no better than presently available P-16 except for solution sprayed barium silicate: lead activated. This phosphor exhibited a relative writing efficiency four times greater than P-16 phosphor on photochromic film.
