Preparation and After-Treatment of BaMgAl10O17:Mn2+

  • Received Date: 2017-03-02
  • BaMgAl10O17:Mn2+ green phosphor was prepared by high temperature solid state reaction and the optimal chemical formula is Ba0.85MgMn0.15Al11.993B0.007O19. The influences of milling and ultrasonic - dispersal on the luminescent properties, granularity and appearance of the phosphor were investigated , and the green phosphor with fine grain and uniform dispersion to be adapted to plasma display panels was obtained. A Hitachi F - 4500 fluorescence spectrophotometer was used to measure the lu-minescent performance of the phosphor , and the vacuum ultra violet (VUV ) fluorescence spectroradio -metric system (Zhejiang University Sensing Instruments Co. , Ltd. ) was used to measure the luminescent performance under 147 nm excitation. A scanning electron microscope (SEM ) was used to identify the size and shape of the particles. X - ray diffraction (XRD ) was used to confirm its crystalline structure. According to this study , the optimal after - treatment processes were as follows: milling time 5 min , milling medium 15 % C2 H5OH , dispersal time 90 min and dispersal medium 15 % C2 H5 OH.

Abstract: BaMgAl10O17:Mn2+ green phosphor was prepared by high temperature solid state reaction and the optimal chemical formula is Ba0.85MgMn0.15Al11.993B0.007O19. The influences of milling and ultrasonic - dispersal on the luminescent properties, granularity and appearance of the phosphor were investigated , and the green phosphor with fine grain and uniform dispersion to be adapted to plasma display panels was obtained. A Hitachi F - 4500 fluorescence spectrophotometer was used to measure the lu-minescent performance of the phosphor , and the vacuum ultra violet (VUV ) fluorescence spectroradio -metric system (Zhejiang University Sensing Instruments Co. , Ltd. ) was used to measure the luminescent performance under 147 nm excitation. A scanning electron microscope (SEM ) was used to identify the size and shape of the particles. X - ray diffraction (XRD ) was used to confirm its crystalline structure. According to this study , the optimal after - treatment processes were as follows: milling time 5 min , milling medium 15 % C2 H5OH , dispersal time 90 min and dispersal medium 15 % C2 H5 OH.
