采用燃烧法合成了一种近紫外激发的Ca3（（P,V）O4）2：Eu^3＋发光材料,用X射线衍射谱、荧光光谱对样品进行了表征。结果表明,荧光粉基质Ca3（（P,V）O4）2具有畸变的Ca3（VO4）2的结构,VO3^4-取代了部分的PO34-,但Ca^2＋的半径与Eu^3＋接近,因此Eu^3＋容易进入晶格,表现出良好的发光性能。荧光光谱分析发现荧光粉可被376 nm紫外光激发,主发射峰值位于620 nm（Eu^3＋离子的5D0→7F2跃迁）的红光,同时详细研究了Eu3＋离子掺杂浓度、引发温度及尿素用量对荧光粉发光性能的影响。

Ca3（（P,V）O4）2：Eu^3＋ phosphor powder with near ultraviolet excitation was synthesized by combustion method.XRD and photoluminescence were employed to characterize their properties.The results showed that the host Ca3（（P,V）O4）2 was presented as a distorted Ca3（VO4）2 structure.A part of PO3-4 was replaced by VO3-4.Due to the similar ion radius of Ca^2＋ ion and Eu3＋ ion,the powders exhibited the strongest emission intensity.The photoluminescence spectra indicated that the phosphor can be excited by UV light（376 nm）,the main emission peak was at 620 nm（Eu3＋ion of 5D0→7F2 transition） of the red light,and the effect of Eu3＋ doping concentration,initiation temperature and the amount of urea on the phosphor luminescent properties was studied.
