    Abstract: In an embodiment, a phosphor material composition comprises a phosphor powder and an additive, wherein the additive has an amount in a range of about 0.1%~20% of the phosphor powder in weight. The material of the additive is selected from the group consisting of an energy absorption material and a conductive material and a combination thereof. In another embodiment, a phosphor material composition including a phosphor powder and an additive is provided, wherein the additive has an amount of 2.8 ppm~32000 ppm. The material of the additive is also selected from the group consisting of an energy absorption material, a conductive material and a combination thereof.

    Abstract: A phosphor capable of being reduced in activity of a surface thereof, to thereby minimize adsorption of gas thereon, release of gas therefrom and the like, to thereby ensure protection of the surface. The phosphor of the present invention is coated with a diamond-like carbon (DLC) film. Such coating reduces an activity of a surface of the phosphor. Also, the phosphor may be used for a display section of a display device. This permits durability of the phosphor to be increased and prevents a deterioration of a cathode, resulting in the display device being increased in durability.

    Abstract: Formation of zinc oxide or indium oxide layer on the surface of a luminophor deposited on a substrate involves adding the luminophor grains to an aqueous solution containing dissolved zinc nitrate or indium nitrate, polyvinyl alcohol (serigraphic binder) and antifoaming agent in water, deposition, and annealing. 1-0.6g of the nitrate and 6-10g of the luminophor are dissolved in 10g of the solution. The luminophor is selected from the following: Gd2O2S:Tb, Y2SiO5:Tb, Y2SiO5:Ce, Y2O3:Eu and ZnO:Zn. Annealing is carried out at 400-500 degrees C for several hours.
