Abstract:
A design for a plasma display panel (PDP). The novel PDP has two separate layers of fluorescent material. One layer of fluorescent material can generate long wavelength from VUV rays and the other fluorescent layer can convert either of VUV or long wavelength ultraviolet rays into visible rays. Such a PDP improves the luminance efficiency by more efficiently using the UV and VUV rays generated during plasma discharge.

Abstract:
A fluorine-containing precoating (not shown) is formed to cover a phosphor particle (7) by, for example, a physical vapor deposition of a fluoride. Then, a fluorine-containing coating (8) covering the phosphor particle (7) is formed by supplying fluorine into the precoating. Thus obtained phosphor particle (7) with the coating (8) is applied in the form of a paste to a substrate (1) on each electrode (2) is between adjacent two ribs (4) to form a phosphor layer (6) including the phosphor particles (7) between the ribs (4) on the substrate (1). The substrate (1) is positioned with respect to another substrate (not shown) having electrodes thereon to form discharge spaces between the substrates. The discharge spade is filled with a discharge gas to produce a plasma display panel (PDP).
