ABSTRACT:
A TFEL structure is disclosed that includes first and second electrode layers sandwiching a TFEL stack including at least one insulator layer and a novel three layer laminate structure. The three-layer laminate structure includes an alkaline earth thiogallate phosphor layer, a nucleating layer and an injection layer. The nucleating layer lies between the phosphor layer and the injection layer. The injection layer provides a charge injection function through the nucleating layer for the thiogallate phosphor layer which is of high crystallinity at its interface with the nucleating layer. A preferred injection layer includes indium, for example as the metal or as indium tin oxide. The best material for the nucleating layer is zinc sulfide.
