| 摘要 |
<p>Ultraviolet-blue excitable phosphor consist of a europium-doped oxynitride host lattice derived from tridymite structure. The lattice has a general composition MAl 2-xSi xO 4-xN x(where M = calcium (Ca), strontium (Sr) or barium (Ba); x = 0.002 - 1.5 (preferably less than 0.7)). The amount of europium (Eu) doped to cation M is 0.1 - 25%.</p> |
