Abstract
PURPOSE: To make possible the improvement in brightness and the increase in dielectric strength by forming mixed layers of ZnS+ZnO at the interface of the vapor deposition layers of sulfide fluorescnet material.
CONSTITUTION: A tin oxide layer 2 provided as a transparent electrode on a glass substrate 1 under vacuum, and yttrium oxide 3 is vapor deposition formed as a dielectric layer thereon. Next, a zinc sulfide layer 4 mixed with activator such as manganese, etc. is evaporated. At this time, the degree of vacuum is lowered and oxygen is intruduced only at the begining and end of the vapor deposition, forming mixed layers 4a, 4a' composed of ZnS+ ZnO. Further a yttrium oxide layer 5 and an aluminum layer 6 as a back electrode are evaporated to complete the device. Hence, the interphase of the fluorescent material layer may be stabilized, leaching of sulfur to the electrode layer side inhibited and the improvement in brightness and the increase in dielectric strength achieved
