摘　　要：采用溶胶凝胶法,合成YF_3/Y_2O_3:Yb^(3+),Er^(3+),Tm^(3+)样品.通过TEM,XRD,Raman及荧光分光光度计对样品的形貌、物相及上转换发光进行表征.结果表明,在980nm激光激发下,Y_2O_3:Yb^(3+),Er^(3+),Tm^(3+)样品在Tm^(3+)掺杂浓度较低时,因Y_2O_3基质具有较大的声子能量,能够实现白色上转换发光.Y_2O_3:Yb^(3+),Er^(3+),Tm^(3+)纳米粒子有望在白色激光器、白色荧光粉及生物医学荧光标记等方面发挥更大的作用.YF3/Y2O3：Yb^03＋,Er^3＋,Tm^3＋nanoparticles were synthesized using the sol-gel method.These nanoparticles were characterized by TEM,XRD,Raman spectroscopy and fluorescence spectrophotometry.The results indicate that Y2O3：Yb^3＋,Er^3＋,Tm^3＋nanoparticles with lower doped concentrations of Tm^3＋ions can emit white upconversion luminescence under a 980 nm CW diode laser excitation due to higher phonon energy of Y2O3 host material.It is therefore concluded that the Y2O3：Yb^3＋,Er^3＋,Tm^3＋nanoparticles have great potential to be used as white laser and white fluorescence bio-labels in the future.
