摘　　要：采用水热法制备了YPxV1-xO4:Eu纳米颗粒,所得粉体用XRD、TEM和光致发光等方法进行了表征。同时,研究了磷元素与钒元素的物质的量的比对粉体发光性能的影响。结果表明:YPxV1-xO4:Eu纳米颗粒属于四方晶相,颗粒尺寸在30 nm左右;磷元素与钒元素的物质的量的比影响Y0.98Eu0.02PxV1-xO4(x=0,0.25,0.50,0.75)粉体的发光性能。YPxV1-xO4：Eu nanoparticles have been prepared by means of a hydrothermal method.The as-synthesized powders were characterized by XRD,TEM and photoluminescence.The influence of the molar ratio of P element to V element on their luminescent properties was also investigated.The results show that the YPxV1-xO4：Eu nanoparticles belong to tetragonal phase,and that the particle size is about 30 nm.The molar ratio of P element to V element of Y0.98Eu0.02PxV1-xO4（x=0,0.25,0.50,0.75） powders has an effect on their luminescent properties.
