Disclosed are an organic electroluminescent device and a preparation method thereof. The organic electroluminescent device is a top-emitting organic electroluminescent device having a reversed structure, and the preparation method is: dissolving zinc oxide with acetic acid to obtain a zinc oxide solution with a concentration of 0.3 g/ml-0.6 g/ml, adding a phthalocyanine substance in a mass of 1%-10% of the mass of the zinc oxide to obtain a mixture, spin-coating the mixture on a glass substrate () and then drying to obtain a cathode (), and then preparing by vapor deposition, an electron injection layer (), an electron transport layer (), a luminescent layer (), a hole transport layer (), a hole injection layer () and an anode (), successively, so as to obtain the organic electroluminescent device.

Organic electroluminescent device and preparation method thereof including forming a cathode by combining zinc oxide, acetic acid and a phthalocyanine substance

Cerium doped magnesium barium tungstate luminescent thin film, manufacturing method and application thereof are provided, said method for manufacturing cerium doped magnesium barium tungstate luminescent thin film comprises the following steps: mixing MgO, BaO, WOand CeO, sintering for forming sputtering target, forming the precursor of cerium doped magnesium barium tungstate luminescent thin film by magnetron sputtering, annealing the precursor of cerium doped magnesium barium tungstate luminescent thin film, and then forming cerium doped magnesium barium tungstate luminescent thin film. Said cerium doped magnesium barium tungstate luminescent thin film exhibits high luminescence efficiency and high light emitting peaks in red and blue regions. Said method presents the advantages of simplified operation, less cost, and suitable for industrial preparation.
