氟钨酸钡荧光体的合成及其发光特性

Synthesis and Luminesecence Properties of Barium Fluorotungstate Phosphors

以ＢａＦ２和ＷＯ３为原料，采用高温固相反应法合成了Ｂａ２ＷＯ３Ｆ４荧光体，测定其Ｘ－射线粉未衍射、激发光谱和发射光谱，探讨了Ｂａ２ＷＯ３Ｆ４及掺杂Ｅｕ３＋离子后荧光体的发光特性。

Investigation of the system BaFZ--wo,shows the existence of a nuorotungstate formulated Ba,WO,F.'Under UV or X-ray excitation,Ba,WO,F.shows an efficient blue-green emission peaking at 480 urn at room temperature'The luminesecence properties show a similarity with those of the tunsgstate,especially MgWO.
