Abstract
A novel thin-film electroluminescent (TFEL) structure for emitting light in response to the application of an electric field is disclosed. The TFEL structure includes first and second electrode layers sandwiching a TFEL stack, the stack including first and second insulator layers and a phosphor layer that includes an alkaline earth thiogallate doped with oxygen.
