Jc. Souriau et al., Cathodoluminescent properties of coated SrGa2S4 : Eu2+ and ZnS : Ag,Cl phosphors for field emission display applications, MAT SCI E B, 76(2), 2000, pp. 165-168
Field emission displays (FED) operate at lower voltages and significantly h
igher current densities than cathode ray tubes (CRTs). This makes it advant
ageous to consider how to adapt conventional CRT sulfur based phosphors, wh
ich have the highest luminescent efficiency, but which unstable under high
electron bombardment, to FED applications. Thus to protect these phosphors
from degradation it is necessary to develop thin layer coatings of stable m
aterials, such as MgO, In2O3 or polyphosphate. The goal of this study is to
investigate the influences of these coatings on the cathodoluminescent pro
perties of the blue phosphor, ZnS:Ag,Cl; and the green phosphor, SrGa4S4:Eu
