| titleOfInvention | Light emitting material for emitting light blue, green, yellow and white light for series field emission displays and preparation method thereof |
| abstract | The invention discloses a light emitting material for emitting light blue, green, yellow and white light for series field emission displays (FED). The chemical composition expression of the material is Li2M1-xEuxSO4 and Li2-yM1-xEuxCeySO4, wherein M is an alkaline earth metal ion selected from Ca<2+>, Ba<2+> and Sr<2+>; Eu<2+> (bivalent rare earth europium ion) and Ce<3+> (trivalent rare earth cerium ion) are active ions; and x and y are molar percentage coefficients of the active ions Eu<2+> and Ce<3+> relative to the alkaline earth metal ion M and range from 0.001 to 0.01. The preparation method of the invention is simple; the novel rare earth light emitting material prepared by the method can emit strong light blue, green and yellow light and white light formed by Eu<2+> emission and Ce<3+> emission under the excitation of a low voltage electron beam; and the display range of fluorescent powder can be obviously expanded by introducing the material into the tricolor fluorescent powder for FED. |
