Abstract

Yttrium fluoride sub-microflowers were synthesized by facile hydrothermal route without using any expensive or environmental unfriendly agents. The influences of various hydrothermal parameters on the final products were investigated. It was found that the concentration of NH₃·H₂O had a significant effect on the morphology change of YF₃ sub-microcrystals. The growth mechanism of the as-obtained YF₃ sub-microflowers was proposed. The multicolor upconversion (UC) photoluminescence (PL) was successfully realized in Yb³⁺/Tm³⁺, Yb³⁺/Ho³⁺ and Yb³⁺/Er³⁺ doped YF₃ sub-microflowers when excited by 980 nm laser diode (LD). The pumping power dependence of the fluorescent intensity is investigated to understand the fundamental UC mechanism.
