由对射出二极管(WLED ) 的白光的新黄磷的需要激发了申请， Ca0.95Nb2 O6 : Eu3+0.05 黄磷被高温度综合固态反应。增加 doped-Eu3+ 的内容并且增加激活剂 Bi3+ 改进 Ca1 的光致发光(PL ) 紧张 ? xNb2 O6Eu3+x 黄磷详细被调查。Eu3+ 的效果比 Ca1 的 PL 紧张上的 Bi3+ 的好 ? xNb2 O6Eu3+x 黄磷。与 Y2O2 S:0.05Eu3+ 相比 Ca0.70Nb2 O6 : Eu3+0.03 黄磷能高效地激动由紫外(395 nm ) 点亮并且与线系列在 614 nm 射出红光，它从在紫外附近与典型排放被联合很好紫外带。染色性协调的 CIE (照明上的国际委员会)(x0.654， y0.348 ) Ca0.70Nb2O6 : Eu3+0.03 接近了 NTSC (国家电视标准委员会) 标准价值。因此 Ca0.70Nb2 O6 : Eu3+0.03 可能发现申请到射出二极管的在紫外附近紫外 InGaN 基于薄片的白光，它被带的制造进一步与 Ca0.70Nb2 O6 证明: Eu3+0.03 黄磷。

英文摘要：

Motivated by the need for new phosphors of white light emitting diode （WLED） application, Ca0.95Nb2O6： Eu0.05^3＋ phosphors were synthesized by high temperature solid-state reaction. Increasing the content of doped-Eu3-- and adding the co-activator Bi3＋ to improve the photoluminescence （PL） intensity of Ca1-xNb2O6：Eux3＋ phosphors were investigated in detail. The effects of Eu3＋ were better than that of Bi3＋ on the PL intensity of Cal-xNb2O6： Eux3＋ phosphors. Compared with Y2O2S：0.05Eu3＋, the Ca0.70Nb2O6.Eu0.03 phosphor could be excited efficiently by UV （395 nm） light and emit the red light at 614 nm with line spectra, which were coupled well with the characteristic emission from UV-Near UV LED. The CIE （International Commission on Illumination） chromaticity coordinates （x=0.654, y=0.348） of Ca0.70Nb2O6： 0.03 were close to the NTSC （National Television Standard Committee） standard values. Therefore Ca0.70Nb2O6.Eu0.03 might find application to UV-Near UV InGaN chip-based white light emitting diodes, which is further proved by the LED fabrication with the Ca0.70Nb2O6.Eu0.03 phosphor.
