    • A display device (10) (Fig. 1) which can be a plasma display panel or a highly loaded fluorescent lamp, comprises a hollow, translucent glass body (12) containing a medium capable of generating at least several wavelengths of UV radiation. A plurality of phosphors is disposed on the inside surface of the glass body, the plurality of phosphors emitting visible radiation upon exposure to the UV radiation. At least one of the plurality of phosphors is subject to degradation upon long-term exposure to one of the at least one of several wavelengths of UV radiation that may be available. The at least one of the plurality of phosphors subject to degradation is installed (Fig. 2) adjacent the inside surface (14) of the glass body to form a first layer (16); and, the remainder of the plurality of phosphors is disposed on the first layer to form a second layer (18), the second layer not being subject to long-term degradation upon exposure to the UV radiation. In some embodiments (Fig. 3) a layer of alumina (20) may first be applied to the inside surface (14) of the glass and the first phosphor (22) applied over the alumina.
    • 可以是等离子体显示面板或高负载荧光灯的显示装置(10)(图1)包括含有能够产生至少几个紫外线辐射波长的介质的中空半透明玻璃体(12)。 多个荧光体设置在玻璃体的内表面上,多个磷光体在暴露于UV辐射时发射可见光。 多个荧光体中的至少一个在长期暴露于可能可用的几种UV辐射波长中的至少一种之一时经历劣化。 所述多个发生劣化的荧光体中的至少一个安装在玻璃体的内表面(14)附近(图2)以形成第一层(16); 并且,所述多个磷光体的其余部分设置在所述第一层上以形成第二层(18),所述第二层在暴露于所述UV辐射时不会长期劣化。 在一些实施例(图3)中,可以首先将一层氧化铝(20)施加到玻璃的内表面(14)上,并将第一荧光体(22)施加在氧化铝上。
