METHOD OF PREPARING DISPERSION TYPE INORGANIC ELECTROLUMINESCENCE DEVICE AND DISPERSION TYPE INORGANIC ELECTROLUMINESCENCE DEVICE

摘要

A dispersion type inorganic electro luminescent device and a manufacturing method thereof are provided to simplify a manufacturing process by integrating a light emitting layer and a dielectric layer. The metal oxide precursor solution is mixed with the fluorescent substance. The metal oxide precursor is coated on a plurality of fluorescent substances with the thickness of 10 to 500nm. The coating is performed by an ultrasonic stirrer, a mechanical stirrer, a magnetic mixer or the homogenizer. A plurality of fluorescent substances are laminated between a transparent electrode(2) and an upper electrode(6). The light emitting layer and the dielectric layer are integrated. An integrated electro luminescent layer(5) is formed. In the metal oxide precursor, the metal oxide is selected from the group made of SiO2, Al2O5, BaTiO5 and TiO2.
