Latest Patents
Juha Viljanen holds a patent for a method of growing a ZnS:Mn phosphor layer suitable for use in thin-film electroluminescent components. The invention relates to a process where the ZnS:Mn phosphor layer is grown on a substrate using the Atomic Layer Epitaxy (ALE) method. This method employs volatile zinc, sulfur, and manganese compounds as precursors. Specifically, an organozinc compound such as diethylzinc or dimethylzinc is utilized for zinc, while hydrogen sulfide or an organosulfur compound serves as the precursor for sulfur. Additionally, an organomanganese compound or organic manganese complex compound is used for manganese. This innovative approach results in a display component that exhibits drive-voltage-symmetrical light emission and stable characteristics of luminance level and turn-on voltage.
