を完成するに至った。The inventors of the present invention have found that a conventional visible light emitting phosphor for a fluorescent lamp has an emission peak wavelength of 200.
It was found that by combining the ultraviolet light emitting phosphors having a wavelength of ~ 400 nm, higher luminous efficiency can be obtained than by directly irradiating the visible light emitting phosphor with short wavelength ultraviolet rays of 147 nm by xenon, and the object of the present invention can be achieved. The present invention has been completed.

The red-emitting phosphors are used alone, but they may be optionally mixed and used according to the purpose.

可視光発光蛍光体の発光効率が下がるからである。The ultraviolet light-emitting phosphor used in the present invention emits long-wavelength ultraviolet light having an emission peak wavelength in the region of 200 to 400 nm when irradiated with short-wavelength ultraviolet light, for example, short-wavelength ultraviolet light of 147 nm emitted from xenon. It is a phosphor. Examples of such an ultraviolet light emitting phosphor include europium-activated strontium borate, europium-activated magnesium phosphate, lead-activated barium silicate and the like. The emission peak wavelength is 200 to 400 nm, for example, around 350 nm. This is because when the emission peak wavelength is less than 200 nm or exceeds 400 nm, the luminous efficiency of the visible light emitting phosphor combined with this decreases.

If the amount is less than 0 part by weight, the amount of the ultraviolet light emitting phosphor is small and the effect cannot be sufficiently obtained. If the amount is more than 50 parts by weight, the emission of the visible light emitting phosphor becomes insufficient.

ィスプレイパネルが得られる。The phosphor of the present invention is used not only in a color plasma display panel but also in a fluorescent lamp of Xe gas discharge. The color plasma display panel of the present invention is characterized by having a phosphor layer made of the above-mentioned phosphor. For example, a paste containing the phosphor is applied to one transparent surface, and a phosphor layer is formed by a conventional method. A color plasma display panel can be obtained by using this as one inner surface to form an enclosed space sandwiched between two parallel surfaces and filled with a xenon-containing gas.

配合した、本発明の蛍光体を用いることが好ましい。The light emitting method using the phosphor of the present invention is as follows. That is, first, short wavelength ultraviolet rays having a wavelength of less than 200 nm are generated. For example, a xenon-containing gas such as helium or neon containing a small amount of xenon is excited to generate ultraviolet rays having a wavelength of 147 nm. This is irradiated onto an ultraviolet light emitting phosphor having an emission peak wavelength in the wavelength range of 200 to 400 nm to generate long wavelength ultraviolet rays in this region. For example, europium-activated strontium borate produces ultraviolet light having a peak wavelength of 360 nm, and lead-activated barium silicate produces ultraviolet light having a peak wavelength of 350 nm. The blue, green or red light emitting phosphor is irradiated with the thus obtained long wavelength ultraviolet ray having the above wavelength to obtain visible light. In order to obtain the highest luminous efficiency, it is preferable to use the phosphor of the present invention in which the above ultraviolet light emitting phosphor and the blue, green or red light emitting phosphor are uniformly blended.
