Abstract

Calculations based on energy ratios and relative luminosities of complementary colors show that the efficiency of white-light production is greatest for the pair of spectral lines at 4590A (violet blue) and 5720A (yellow green). Spectral distribution curves of relative absorption and emission are given for the zinc-cadmium sulphide phosphor systems and for typical white kinescope screens.

E λ 1 = L 1 / L λ 1             and             E λ 2 = L 2 / L λ 2 .
E 4745 = 7.3 / 0.1126 = 64.9 and E 5755 = 67.7 / 0.9069 = 74.7.
E T = E λ 1 + E λ 2
E 1 = E λ 1 / E T and E 2 = E λ 2 / E T .
E T = 64.9 + 74.7 = 139.6 , E 1 ( 4745 ) = 64.9 / 139.6 = 46.5 % , E 2 ( 5755 ) = 74.7 / 139.6 = 50.6 % .
