Abstract: A method of forming a fluorescent screen, such as a black matrix or a color filter, on a front panel of a cathode ray tube is described. The method comprises the steps of forming a photosensitive adhesion layer on an inner surface of the front panel, exposing the photosensitive adhesion layer through a color selecting electrode having a plurality of slots for reducing adhesion level of exposed area of the photosensitive adhesion layer, bringing a pigment layer provided on a supporting sheet into intimate contact with the photosensitive adhesion layer, applying pressure to the pigment layer and the photosensitive layer, and peeling off the supporting sheet from the pigment layer. Alternatively, a pigment may be dispersed in the photosensitive adhesion pigment layer. In the case, the photosensitive adhesion pigment layer is brought into intimate contact with the inner face of the front panel and exposed through a color selecting electrode, followed by the steps of applying pressure and peeling off a supporting sheet from the photosensitive adhesion pigment layer.

Abstract: The fluorescent material is prepared by co-activating yttrium oxide fluorescent material activated with europium. The means particle size is 10 nm to 100 nm. To prepare the fluorescent material, basic carbonate activated with europium and zinc is used as a precursor which is then baked. The precursor is prepared by a liquid-phase reaction. Specifically, yttrium nitrate, europium nitrate and zinc acetate are allowed to react in a solution together with sodium carbonate. The prepared precursor is baked by a quick heating and cooling. As an alternative to this, the precursor is baked together with flux (phosphate of alkali metal). The fluorescent material is excellent in the intensity of color and brightness and suitable for a FED and a precise CRT.

Abstract: PROBLEM TO BE SOLVED: To obtain a fluorescent substance, excitable at a low voltage and suitable for thin-film displays by coating fluorescent particles having nano- structural crystals with a glassy component. SOLUTION: This fluorescent substance 1 is obtained by coating fluorescent particles 2 having nano-structural crystals with a glassy component 3. One of the examples of the fluorescent particles 2 is zinc sulfide, approximately 3 nm in diameter, doped with an activator. The activator for zinc sulfide is of terbium(Tb), europium(Eu), fluorine(F), or the like. The glassy component 3 is preferably in the form of gel or the like, obtained by polymerizing tetraethoxysilane in ethanol, ion-exchanged water or hydrochloric acid. The fluorescent substance 1 can be produced by, e.g. reacting the fluorescent particles 2, obtained by the liquid-phase reaction in which coprecipitation or the like is involved, with the glassy component 3 in the form of gel to coat the particles 2 with the glassy component 3.
