The dull and stereotyped display (PDP) of colored plasma body because it has a lot of fine performance, become one of the colored displays with development prospect. Improve the performance of PDP, use the research of three base color phosphor powder to be essential to PDP.
高温固相法制备绿色荧光粉BaA112019:Mn2+是目前工业生产的首选。但由于其制备的荧光粉颗粒不均匀、易团聚、分散性差等缺点。使其无法达到显示技术的要求。
The high-temperature firm looks law prepares green phosphor powder BaA112019: Mn2 is + the first-selection of industrial production at present. The intersection of phosphor powder and the intersection of particle and irregularity that prepare its, exchange reunion, the intersection of dispersiveness and shortcoming such as being poor. Make it not can't reach the requirement which reveals technology.
本论文采用高温固相法制备出发光强度较高的PDP用绿色荧光粉BaA112019:Mn2+。并通平行实验法和正交实验设计两种实验方法对最佳后处理实验条件进行了选择。发现小分子酸溶液、超声处理、溶剂与粉体比列都对荧光粉各性能存在影响。
This thesis adopts the high-temperature firm looks law to prepare luminous intensity higher PDP of setting out and use green phosphor powder BaA112019: Mn2+. And open parallel the intersection of experiment and law and orthogonal the intersection of experimental design and two the intersection of experiment and method go on and choose to best the intersection of aftertreatment and the intersection of experiment and terms. Find it is influenced that small molecule acid solutions, supersound dealing with, solvents compared with body of powder lists to exist phosphor powder every performance.
通过PDP荧光粉测试系统测试荧光粉的发光性能，环境扫描电镜下观测并拍摄了荧光粉的晶粒尺寸和形貌，平均粒径分析仪测定荧光粉的平均粒径， X-射线粉晶衍射仪（XRD）测定粉体的物相构成。
Test the luminescence performance of the phosphor powder of system testing through PDP phosphor powder, the environment scans size and topography of crystalline grain that has observed and shot the phosphor powder under the electric mirror, average analysis instruments of foot-path determine the average foot-paths of the phosphor powder, X - the intersection of ray and the intersection of powder and brilliant the intersection of diffraction and appearance determine powder thing of body form.
从结果分析得到，粉体经过后处理，其发光强度、粒径、分散性、稳定性，都得到较大改善。弥补了高温固相法制备绿色荧光粉BaA112019:Mn2+的不足。
Analyze from the result and get, the body of powder passes aftertreatment, its luminous intensity, a foot-path, dispersiveness, stability, get greater improvement. Remedying the high-temperature firm looks law prepares green phosphor powder BaA112019: Deficiency of Mn2 +.

The colour plasma flat display (PDP) has a lot of good function because of the person , becomes one
of the colour display developing a prospect have most. Need to improve the PDP function, the
research using three primary colours fluorescent powder to PDP is all-important. High temperature
strengthen method of physiognomy preparation green fluorescent powder BaA112019: Mn2 + is that the
commercial run head elects at present. But since whose the preparation fluorescent powder pellet is
uneven, exchange birdnesting , the disperse low grade shortcoming. Make the person have no way to
reach the request demonstrating a technology's. The thesis adopt capital high temperature
strengthen method of physiognomy preparation starting off with green fluorescent powder BaA112019
up higher PDP of intensity: Mn2 +. And know the experiment law and orthogonality experiment of
equal rank designing that two kinds experiment method have carried out choice on the best
post-processing experiment condition. Discover the sour small molecule solution , surpass sound
treatment , menstruum and the powder body than every there exists effect in function column all to
fluorescent powder.
By the fact that PDP fluorescent powder tests the system testing fluorescent powder luminescence function, the environment scanning electricity has observed and shot fluorescent powder crystallite dimension and shape appearance under the mirror, the average grain size analysis instrument determines average fluorescent powder grain diameter , the thing determining the powder body composes the X-ray powder crystal diffraction instrument (XRD) each other. Secondary result analysis gets , powder experiences and observes the course post-processing, whose luminescence intensity , grain diameter , disperse , stability, get bigger improvement. Reparation high temperature strengthen method of physiognomy preparation green fluorescent powder BaA112019: Mn2 + deficiency. Keywords: The green fluorescent powder post-processing orthogonality experiment designs the glowing function
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.

Color flat-panel plasma display panel (PDP) has many because of its excellent performance, becoming the most promising one color monitors. To improve the performance of PDP, the PDP with the three primary colors phosphor research is essential.
Preparation of high-temperature solid-state green phosphor BaA112019: Mn2 + industrial production is the first choice. However, due to its uneven preparation of the phosphor particles, the easier reunion, poor dispersion of shortcomings. So that it can not meet the requirements of display technology.
The high temperature solid-state papers prepared by starting the PDP high-intensity green phosphor BaA112019: Mn2 +. Experimental and parallel-law and two orthogonal experimental design the best method of treatment after the experimental conditions were chosen. Found that small molecule acid solution, ultrasound treatment, powder and solvent than are listed on the phosphor of the existence of impact.
PDP phosphor through the test system testing Phosphor Properties, environmental scanning electron microscope observation and took the phosphor grain size and morphology, the average particle size analysis to measure the average size of the phosphor, X-ray powder Crystal diffraction (XRD) phase of the powder form. Results from the analysis, after handling the powder, its luminous intensity, size, dispersion and stability, have been greatly improved. Compensate for the high-temperature solid-state prepared by the green phosphor BaA112019: Mn2 + deficiencies.
