초록
The electric properties of porous phosphor layers for plasma display panels were studied, which generated typical RGB colors from vacuum ultraviolet light; red is (Y,Gd)BO3 : Eu3+ (YGB), green is Zn2SiO4 :Mn2+ (ZSM), and blue is BaMgAl10O17 : Eu2+(BAM). Because the phosphors were not fully packed in cells of a plasma display panel (PDP), their electrical properties were measured using an appearance density of approximately 60%. There was only a slight difference in the dielectric constants of the RGB phosphors; however, the dielectric loss of the green phosphor was much larger than that of either the blue or red phosphors. The volumetric resistivity of the powders had increasingly lower values according to the emission wavelengths of the phosphors.
Abstract
The electric properties of porous phosphor layers for plasma display panels were studied, which generated typical RGB colors from vacuum ultraviolet light; red is (Y,Gd)BO3 : Eu3+ (YGB), green is Zn2SiO4 :Mn2+ (ZSM), and blue is BaMgAl10O17 : Eu2+(BAM). Because the phosphors were not fully packed in cells of a plasma display panel (PDP), their electrical properties were measured using an appearance density of approximately 60%. There was only a slight difference in the dielectric constants of the RGB phosphors; however, the dielectric loss of the green phosphor was much larger than that of either the blue or red phosphors. The volumetric resistivity of the powders had increasingly lower values according to the emission wavelengths of the phosphors.
