摘要

(57) Abstract The oxidation gallium where the one for electroluminescence display material is doped, the alkaline earths salt of the gallium Acid and the new oxide phosphor which is based on germanate. First, electroluminescence of discernment red amorphous and crystal Characteristic oxide Ga₂ O₃: It could in Eu. 1 - 8 mols % SrGa₂ O_{4 which} dopes Eu and Tb and SrGa₄ O₉, 1 - 4 mols % CaGa₂ O_{4 which} dopes Eu, Tb, PR and Dy, Ca₃ Ga₂ O₆ and CaGa₄ O₇, 1 - 2 mols % BaGa₂ O_{4 which} dopes Eu and Tb was prepared on the ceramic dielectricity base material making use of RF magnetron sputtering, at 600 - the 950 1 - 2 hour annealings was done in air or Ar. You could obtain the bright electroluminescence (EL) radiation where it possesses the wavelength which covers the visible spectrum 400 - 700nm you could obtain the infrared radiation above 700nm which possesses feature spectrum peak in rare earth succession. 1 mols % the film of CaGa₂ O_{4 which} possesses Eu achieved 22fL (75cd/m2) with 60Hz, had possessed the maximum efficiency of 0.2lm/w vis-a-vis red radiation. 2 mols % the amorphous thin film of Ca₃ Ga₂ O_{6 which} possesses Eu, when annealing it does with the 600, achieved 34fL with 60Hz in red EL. 1 mols % Eu and 4 mols % SrGa₂ O_{4 which} possesses Tb has red, green color and blue radiation (with 60Hz 13fL), white phosphor was brought, 8 mols % SrGa₂ O_{4 which} possesses Tb brought the phosphor of the blue color and green color of 30fL with 60Hz. It sputtered Zn₂ Si_0.5 Ge_0.5 O_{4 which} contains Mn making use of the magnetron RF sputtering to on the ceramic dielectricity base material, at the 700 1 hour annealings did in the air or argon. You could obtain bright green (540nm) radiation in the electroluminescence: With 60Hz 110fL (377cd/m2 and maximum efficiency 0.9l/w). Also bright red radiation (640nm) in was obtained.
