Research Abstract

Inorganic see-through thin-film electroluminescent (TFEL) devices were fabricated using an oxide phosphor emitting layer prepared on a transparet ceramic and/or ultla thin grass sheet substrate. A high-luminance in green emission was obtained in a single-insulating-layer-type or double-insulatinglayer type TFEL device fabricated using a postannealed Zn2Si0.6Ge0.4O4:Mn thin film deposited on a. Bendable and see-through Zn2Si0.6Ge0.4O4:Mn TFEL lamps were demonstrated using a double-insulating-layertype device fabricated on a transparet ceramic and/or ultla thin grass sheet substrate with a thickness of approximately 6000 nm.
