摘　　要：以硝酸钇、硝酸铕和磷酸二氢铵为反应前躯体,等摩尔的硝酸钠和硝酸钾为反应介质,采用熔盐法合成了YPO4∶Eu纳米棒束(1)。XRD研究表明,1在300℃开始结晶,450℃结晶完全;SEM,TEM和HR-TEM研究表明,1主要是由结晶度高的纳米棒组成的纳米棒束,尺寸分布均匀,纳米棒束宽50 nm^60 nm,长1 000 nm^1 500nm;发射光谱和激发光谱研究表明,随着焙烧温度的升高,1的荧光性能增强;最佳Eu3+的掺杂量为5 mol%。YPO4 ∶Eu nanorod-clusters（1） was successfully synthesized by molten-salt method in equal moles of NaNO3 and KNO3 using Y（NO3）3,Eu（NO3）3 and NH4H2PO4 as the precursors.XRD detection results indicated that 1 began to crystallize at 300 ℃ and fully crystallized at 450 ℃.SEM,TEM and HR-TEM detection results showed that 1 are highly crystalline nanorod-clusters formed by nanorods with width of 40 nm^50 nm,length of 1 000 nm^1 500 nm.Emission and excitation spectra detection results showed the PL intensity of 1 increases with increase of calcination temperature and the optimum doping amount of Eu3＋ is 5 mol%.
