摘要： An AC thin film electroluminescent (TFEL) device includes a multilayer phosphor for emitting white light having improved emission intensity in the blue region of the spectrum. The multilayer stack consists of an inverted structure thin film stack having a red light emitting manganese doped zinc sulfide (ZnS:Mn) layer disposed on a first insulating layer; a blue-green light emitting cerium doped strontium sulfide (SrS:Ce) layer disposed on the red light emitting layer; and a blue light emitting cerium activated thiogallate phosphor (Sr.sub.x Ca.sub.1-x Ga.sub.2 S.sub.4 :Ce) layer disposed on the blue-green light emitting layer. The manganese doped zinc sulfide layer acts as a nucleating layer that lowers the threshold voltage, and the cerium activated thiogallate phosphor layer provides a moisture barrier for the hydroscopic cerium doped strontium sulfide layer. The white light from the multilayer phosphor can be appropriately filtered to produce any desired color.

摘要： 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.

摘要： A process for fabrication and annealing of TFEL panels includes the steps of depositing a laminar stack of thin films on a glass substrate containing a first set of electrodes, the laminar stack comprising at least one insulating layer and an EL phosphor layer and annealing the laminar stack under an array of high intensity flash lamps at a temperature exceeding 450.degree. C. for a period of between 15 and 240 seconds. The flash lamps bring the temperature of the laminar stack to the required high temperature very quickly and the stack is cooled very quickly at the end of the annealing period. This process conditions the EL phosphor layer but does not warp the glass substrate or damage the thin films.
