Abstract

A series of BaZnF

:Er

upconversion luminescence nanoparticles with various doping concentrations were synthesized

via

thermal decomposition method. X-ray diffraction (XRD)

transmission electron microscope (TEM) and fluorescence spectrophotometer were used to investigate 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%Er

and 20%Yb

are the best doping 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
