Yes. The ultraviolet light generated by the discharge of Xe gas includes Xe resonance line (wavelength 146 nm) and Xe ₂ molecular beam (wavelength 172 nm).

ＡＣ型ＰＤＰは、画像表示面となる前面板と、Ｘｅガスを含む放電ガスが充填された放電空間を挟んで対向配置された背面板とから構成されている。ＡＣ型ＰＤＰでは、背面板は、一般に、基板（通常は、ガラス板）と、基板の上に形成されたアドレス電極と、アドレス電極を被覆する誘電体層と、誘電体層の上に形成された隔壁とからなる積層体を基体として、その基体の誘電体層表面と隔壁側面の上に蛍光体層が形成された発光性積層体である。背面板の蛍光体層は、隔壁によって青色発光蛍光体層、緑色発光蛍光体層及び赤色発光蛍光体層の三色の蛍光体層に仕切られており、各色の蛍光体層の蛍光体を励起させることにより発光した青色、緑色、赤色の可視光の組み合わせにより画像を表示する。 The AC type PDP is composed of a front plate serving as an image display surface and a back plate disposed opposite to each other across a discharge space filled with a discharge gas containing Xe gas. In the AC type PDP, a back plate is generally formed on a substrate (usually a glass plate), an address electrode formed on the substrate, a dielectric layer covering the address electrode, and the dielectric layer. A light emitting laminate in which a phosphor layer is formed on the dielectric layer surface of the substrate and the side walls of the laminate using the laminate comprising the barrier ribs as a substrate. The phosphor layer of the back plate is divided into three color phosphor layers, a blue light-emitting phosphor layer, a green light-emitting phosphor layer, and a red light-emitting phosphor layer, by partition walls, and excites the phosphor of each color phosphor layer. The image is displayed by a combination of blue, green, and red visible light emitted.

Ｘｅランプは、一般に、管状ガラスやガラス製筐体を基体とし、その内側に蛍光体層を形成した発光素子内に、放電ガスを充填した構成となっている。Ｘｅランプでは、発光素子が発光性積層体である。発光素子の蛍光体層は、通常は、青色発光蛍光体、緑色発光蛍光体及び赤色発光蛍光体を混合した蛍光体混合物から形成されている。 In general, the Xe lamp has a configuration in which a discharge gas is filled in a light emitting element having a tubular glass or a glass casing as a base and a phosphor layer formed inside thereof. In the Xe lamp, the light emitting element is a light emitting laminate. The phosphor layer of the light emitting element is usually formed from a phosphor mixture in which a blue light emitting phosphor, a green light emitting phosphor and a red light emitting phosphor are mixed.

特許文献１には、ＡＣ型ＰＤＰの蛍光体層に、Ｘｅガスの放電により生成する紫外光により励起されて２３０〜２５０ｎｍの波長範囲にピークを有する紫外光を発光する酸化マグネシウム結晶体を添加すると、酸化マグネシウム結晶体によって放出された紫外光によっても、蛍光体層中の蛍光体が励起されるので、輝度が向上することが開示されている。 In Patent Document 1, a magnesium oxide crystal that emits ultraviolet light having a peak in a wavelength range of 230 to 250 nm excited by ultraviolet light generated by discharge of Xe gas is added to a phosphor layer of an AC type PDP. It is disclosed that the luminance is improved because the phosphor in the phosphor layer is also excited by the ultraviolet light emitted by the magnesium oxide crystal.
