colored plasma flat-panel display (PDP), because it has many fine performance, becomes most has one of prospects for development colored monitors. Must enhance PDP the performance, uses three primary color luminous powder to PDP the research to be very important. The high temperature solid phase legal system prepares green luminous powder BaA112019:Mn2+ is the present industrial production first choice. But because its preparation's luminous powder pellet non-uniform, easy to reunite, the dispersivity badly and so on shortcomings. Causes it to be unable to achieve the display technology the request The present paper uses the high temperature solid phase legal system to prepare embarking light intensity high PDP to use the green luminous powder BaA112019:Mn2+. And passed the parallel cut-and-try method and the orthogonal experimental design two experimental techniques has carried on the choice to the best post-processing experimental condition. Discovered that the small molecular acid solution, supersonic processing, the resolver and the powder body compare the row to the luminous powder various performance existence influence. Crossed the PDP luminous powder test system test luminous powder the illumination performance, under the environment scanning electron microscope observes and has photographed the luminous powder grain size and the appearance, the average grain diameter analyzer determination luminous powder's average grain diameter, the X- beam powder crystal diffractometer (XRD) determined the powder body's phase constitution. Obtains from the result analysis, the powder body after the post-processing, its luminous intensity, the particle size, the dispersivity, the stability, obtains improves greatly. Made up the high temperature solid phase legal system to prepare green luminous powder BaA112019:Mn2+ the insufficiency. 绿色荧光粉 Green luminous powder后处理 post-processing正交实验设计 orthogonal experimental design发光性能illumination performance
