Electrooptical properties of d.c. electroluminescent ZnS:Mn,Cu powder panels with chalcogenide glass intermediate layer

摘要

Introducing of amorphous (a) a-As2Se3as contrasting intermediate layer into SnO2-As2Se3-ZnS(Mn, Cu)-Al structure allows one to increase by about 50% a light contrast range of the device that facilitates the perception of symbol-alphabetic information. The bleaching of а-As2Se3film under the action of humidity allows one to control the state of the structure air-tightness. The absorption edge of As-Se films and electrooptical characteristics of SnO2-ZnS(Mn, Cu)-Al active structure have been investigated
