Latest Patents
Marja Leppa/Nen holds a patent for a "Method for preparing a multilayer structure for electroluminescent." This patent describes a method for fabricating a multilayer alkaline-earth sulfide-metal oxide structure that is particularly suited for use in electroluminescent components. The method involves forming a multilayer structure that includes at least one phosphor layer and at least one dielectric layer on a suitable substrate. The phosphor layer consists of at least one alkaline-earth sulfide, while the dielectric layer comprises at least one metal oxide. Notably, at least one of the dielectric layers is deposited through surface reactions directly onto the alkaline-earth sulfide layer(s). This innovative approach utilizes an organometal complex as a precursor, avoiding compounds that could negatively react with the alkaline-earth sulfide layer. As a result, the electroluminescent component structure exhibits a longer lifespan compared to prior art.
