Abstract

A series of NaYF

:20%Yb

1%Tm

upconversion particles (UCPs) with different morphology were prepared by the facile hydrothermal approach. The morphology

crystalline phase and optical properties were characterized by scanning electron microscopy (SEM)

X-ray diffraction (XRD) and luminescent spectra. XRD patterns and SEM images showed that the UCPs crystalline phase tansformed from cubic phase to hexagonal phase by controlling the reactants concentration. Pumped with 980 nm diode laser

the UCPs emitted bright violet/blue upconversion luminescence. By analyzing the effect of reactants concentration on the products crystalline phase

the crystal growth mechanism of NaYF

was studied in detail. Significantly

our research work would provide more experimental data for controlling the crystalline phase of the upconversion luminescent materials.
