    摘要： A fluorescent material and a display device incorporating the fluorescent material are described. The fluorescent material is a mixture including a phosphor which is excitable at a voltage of 1 kV or higher for emitting light and a phosphor which is excitable at a voltage of 1 kV or lower for emitting light, wherein each phosphor emits light of the same color and the fluorescent material is luminous at an anode voltage of 2 kV or lower. The fluorescent display device accelerates electrons emitted from an electron source at an anode voltage of 2 kV or lower and rushes these electrons against an anode for exciting the fluorescent material present on the anode. The fluorescent material is a mixture as set forth above.

    摘要： A method for preparing a gallium nitride phosphor which is capable of emitting light at luminance increased to a degree sufficient to permit the phosphor to be practically used. A dopant compound containing elements reacted with H2 and gasified by heating is arranged on an upstream side in a calcination oven in which NH3 is flowed and a matrix element compound is arranged on the downstream side therein, resulting in calcination of the compound being carried out. This permits GaN to be surrounded with ammonia and the dopant during the calcination, so that the GaN phosphor may be fully doped with the dopant.

    摘要： A phosphor in the form of a columnar powder capable of exhibiting enhanced luminous efficiency, providing various luminous colors by electron excitation depending on the selection of elements added thereto and having improved life characteristics. The phosphor is made by heating a starting material constituted by a GaN based phosphor material to a temperature equal to or greater than a sublimation temperature thereof. The phosphor thus obtained is represented by Ga1−xInxN:A,B, wherein x is larger than or equal to 0 and smaller than 1 (0≦x

    摘要： The present invention provides a phosphor of formula A2SiO5:B (A is Y or Gd, and B is Ce or Tb) which is characterized by a surface elemental composition represented by (A+B)/Si ranging from 1.5 to 2.5, wherein A is Y or Gd, and B is Ce or Tb; and method for preparing said phosphor. One embodiment of the method is as follows: a SiO2 powder is mixed with co-precipitate (Y, Ce)2O3 (Ce/Y=0.01), in an amount ranging from 10 to 110 mol % based on the amount of (Y, Ce)2O3, and the mixture is charged into the inner crucible of a double-walled aluminum crucible. After graphite is charged between the inner and outer crucible, the mixture is calcined at 1450° C. for 2 hours to obtain an Y2SiO5:Ce phosphor. The luminous efficiency of a field emission display (FED) prepared employing the Y2SiO5:Ce phosphor was measured at an anode voltage of 600V, an electric power input of 30 Wp-p and a duty rate of 1/240. It is desirable that the relative amount of SiO2 based on the amount of (Y, Ce)2O3 ranges from 40 to 70 mol %, preferably 50 to 60 mol %.
