摘要：

The (Zn0.27, Cd0.73)S:Ag, Cl, (Zn0.77, Cd0.23)S:Cu, Cl and Y2O2S:Eu3+ red-light emitting phosphors have been used in the preparation of cathode-ray tube screens for television. The dependence of screen brightness on both electron-beam accelerating voltage and current densities has been studied. The theoretically calculated intrinsic efficiencies are compared with the experimental efficiencies. The chromaticity of the cathode-ray tube screens was also studied as a function of accelerating high tension and current density. Cathodoluminescence emission spectra for these phosphors at room temperature are also measured. © 1990 Chapman and Hall Ltd.
