ALUMINATE-BASED BLUE PHOSPHORS |
| 摘要 |
<p>Embodiments of the present invention are directed in general to novel aluminate-blue phosphors; specifically, use in white light illumination systems, and in display applications such as back lighting in liquid crystal displays (LCD's) and plasma display panels (PDPs). Embodiments of the present invention are further directed toward aluminate-based phosphors having the general formula (M<SUB>1</SUB>-<SUB>X</SUB>Eu<SUB>x</SUB>)<SUB>2</SUB>-<SUB>Z</SUB>Mg<SUB>Z</SUB>Al<SUB>y</SUB>O<SUB>[1+(3/2)y]</SUB>, where M is a divalent alkaline earth metal other than magnesium (Mg) from group IIA of the periodic table, where 0.05<x<0.5; 3=y=12; and 0.8=y =1.2. In another embodiment, 0.2<x<0.5. The composition may contain a halogen, such as fluorine or chlorine. M may be either Ba (barium) or Sr (strontium); when M is Ba, the phosphor is a member of the present barium aluminate magnesium (BAM) series; when M is strontium, the phosphor is a member of the present strontium magnesium aluminate (SAM) series.</p> |
