Abstract

YF₃:Yb³⁺(20%)/Tm³⁺(2%) octahedral nanocrystals were synthesized by a microemulsion method with NH₄HF₂. Pumped with a 980-nm diode laser, the nanocrystals emitted weak blue and intense ultraviolet light. Especially, unusual ³P₂ →³H₆ (∼265 nm) and ³P₂ →³F₄ (∼309 nm) emissions, coming from a five-photon excitation process, were observed. The emissions from ¹D₂ and ¹I₆ were much stronger than those from ¹G₄ and ³H₄. The upconversion mechanism was discussed in detail.
