Optical properties of the BaMgAl_(10)O_(17):Eu~(2+) phosphor coated with SiO_2 for a plasma display panel

摘要

In order to improve the luminance of blue emission of the plasma display panel (PDP), BaMgAl_(10)O_(17):Eu~(2+) (BAM) phosphors were synthesized and were coated with SiO_2. It was revealed that the surface coating of phosphors with SiO_2 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 SiO_2. The experimental results suggest that the surface coating of BAM with SiO_(2a) is a way to improve the luminance of the PDP.
