- 論文の詳細を見る
A blue-light-emitting Eu^2+ doped CaMgSi_2O_6 phosphor with a long lifetime for a plasma display panel (PDP) was developed. The CaMgSi_2O_6:Eu^2+ (CMS:Eu^2+) phosphors synthesized using SiO_2-rich source materials show no luminance degradation during the baking process for binder burn-off, and the photoluminescence peak intensity of the Eu^2+ emission band is higher than that of conventional blue phosphor BaMgAl_10O_17:Eu^2+ (BAM) after the baking process. The test PDP using synthesized CMS:Eu^2+ phosphor shows a comparable emission peak intensity to that of BAM , while the luminance of the CMS:Eu^2+ panel is approximately 55% that of the BAM panel due to the narrower spectral bandwidth and shorter peak wavelength. The CMS:Eu^2+ panel shows less luminance degradation than BAM under the aging test, and the CMS:Eu^2+ panel retains 85% of its luminance after 300 hours driving. It is found that CMS:Eu^2+ appears to be a promising blue phosphor material for PDP.
