球形BaZnF4:Yb,Er纳米颗粒的热分解法合成及其上转换发光性质
Thermal Decomposition Synthesis and Upconversion Luminescence Properties of Spherical BaZnF4:Yb,Er Nanoparticles
摘要
Abstract
A series of BaZnF4:Er3+,Yb3+ upconversion luminescence nanoparticles with various do-ping concentrations were synthesized via thermal decomposition method. X-ray diffraction ( XRD) , transmission electron microscope ( TEM ) and fluorescence spectrophotometer were used to investi-gate the morphology, crystal structure and upconversion properties of the samples. The morphology of the sample is ball shape with an average size about 8 nm. 4%Er3+and 20%Yb3+ are the best do-ping mole fraction. Red and green emissions were observed for the synthesized samples under 980 nm excitation. The red and green emissions are corresponding to the transitions 2 H11/2→4 I15/2 ( Green) , 4 S3/2→4 I15/2 ( Green) of Er3+, 4 F9/2→4 I15/2 ( Red) of Er3+ ions, respectively.关键词
