Abstract

In this paper, highly crystalline YF₃:Yb³⁺/Ln ³⁺ (Ln = Er³⁺, Tm³⁺) microsheets were successfully synthesized by a surfactant-free molten salt method for the first time. The results indicated that the as-obtained samples belonged to orthorhombic system and exhibited microsheets morphology with side lengths of 30 to 80 μm and wall thickness from 1 to 1.5 μm. By changing the dopant's species (Ln³⁺), multicolor (yellow and blue) upconversion emission can be observed in YF₃:Yb³⁺/Ln³⁺ microsheets under 980 nm laser diode (LD) excitation. The upconversion mechanisms in co-doping YF₃ samples were analyzed in detail based on the emission spectra. Importantly, this approach not only proposes a new alternative in synthesizing such materials, but also opens the possibility to meet the increasing commercial demand.
