Optical properties of the BaMgAl10O17:Eu2+ phosphor coated with SiO2 for a plasma display panel

In order to improve the luminance of blue emission of the plasma display panel (PDP), BaMgAl10O17:Eu2+ (BAM) phosphors were synthesized and were coated with SiO2. It was revealed that the surface coating of phosphors with SiO2 leads to an increase in luminance intensity of PDP devices. This seems to...

Description
Summary:In order to improve the luminance of blue emission of the plasma display panel (PDP), BaMgAl10O17:Eu2+ (BAM) phosphors were synthesized and were coated with SiO2. It was revealed that the surface coating of phosphors with SiO2 leads to an increase in luminance intensity of PDP devices. This seems to be due to the increase of the excitation light which is transmitted into the phosphor, i.e., an effective vacuum ultraviolet absorption of the phosphor via SiO2. The experimental results suggest that the surface coating of BAM with SiO2a is a way to improve the luminance of the PDP.
