Abstract

A facile hydrothermal method is used for the preparation of Tm³⁺/Yb³⁺ codoped fluoride microphosphors. The effect of crystal structure and ions concentration on the spectra and lifetimes of the radiative levels of Tm³⁺ ions in the different fluoride microcrystals is studied in detail. XRD analysis of Tm³⁺/Yb³⁺ codoped LaF₃ microcrystals shows that 20% Yb³⁺ doping is sufficient for hexagonal LaF₃ microparticles to crystallize completely in the orthorhombic phase. And lifetime analysis suggests that the average lifetimes of the radiative levels of Tm³⁺ ions increased when the matrix phase structure changing from orthorhombic phase to hexagonal phase with ytterbium dopant concentration changing.
