Provided are a phosphor-containing capable of suppressing deterioration of phosphors and can be manufactured with high efficiency and a backlight unit. Specifically, provided is a phosphor-containing film, including a first substrate film; and a phosphor-containing layer at which a plurality of regions containing phosphors, which, if exposed to oxygen, deteriorate by reacting with the oxygen, are discretely disposed on the first substrate film, and at which a resin layer having an impermeability to oxygen is disposed between the discretely disposed regions containing phosphors, in which a width S of the resin layer between the regions containing phosphors is 0.01S<0.5 mm, and wherein a ratio of a volume Vp of the regions containing phosphors, to a sum of the volume Vp and a volume Vb of the resin layer in the phosphor-containing layer, is 0.1Vp/(Vp+Vb)<0.9.

An enhanced vision system includes an image intensifier that includes a phosphor screen. The phosphor screen includes a thin-film phosphor layer deposited, patterned, transferred, or otherwise disposed on the substrate using a thin-film deposition technique. A conductive layer is deposited across at least a portion of the phosphor layer. The relatively smooth morphology of the phosphor layer beneficially permits the use of a relatively thin conductive layer. The use of a relatively thin conductive layer advantageously reduces the operating voltage between an electron multiplier and the phosphor screen. A secondary electron emitter may be disposed across at least a portion of the conductive layer.
