Study on the degradation of blue phosphor for color PDPs

摘要

The BAM (BaMgAl{sub}10O{sub}17:Eu{sup}(2+)) solid solution with the barium-poor aluminate (Ba{sub}0.75Al{sub}11O{sub}17.25) developed in the present work shows the strong resistant property to the thermal degradation, such as luminous efficiency and the color coordinates compared to the conventional BAM. From adopting the BAM solid solution system for color PDPs, it is confirmed that the maintenance rate for the luminous degradation and the alteration of the color coordinate y value after heat treatment is improved to be about 1.3 times of those of the conventional BAM, respectively.
