— Quantum efficiencies in the vacuum ultraviolet, chromaticities, and decay times of a number of highly efficient green phosphors for plasma‐display applications are compared. It is shown that the Tb 3+ ‐activated phosphates offer improved quantum efficiencies relative to those of the standard plasma‐display phosphor, Zn 2 SiO 4 :Mn, for applications where 10‐ms decay times are acceptable. For applications requiring a very fast response, a new Eu 2+ ‐activated strontium aluminate is found to provide an efficient green phosphor whose efficiency is about 40% of the best phosphate but with a luminescence decay time of only 5 μs.
