Title:
PLASMA DISPLAY DEVICE AND METHOD FOR MANUFACTURING GREEN PHOSPHOR MATERIAL FOR PLASMA DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2007/097399
Kind Code:
A1
Abstract:
Provided is a plasma display device having a novel phosphor layer which emits green
light and improved initial emission luminance and improved emission luminance maintaining
rate. The phosphor layer includes a mixture of particles of Zn2SiO4:Mn and
particles of (Y, Gd)BO3:Tb. The surface of the particles of Zn2SiO4:Mn is
covered with aluminum oxide. The ratio of Al to Si measured by an X-ray photoelectron spectroscopy
(XPS) apparatus on the particle surface is 0.6 or more but not more than 7.0.
