Abstract

The upconversion luminescent properties of YF₃:Yb³⁺(20%)/Tm³⁺(1%) nanobundles with different sizes (240-500 nm in length) were studied under 980-nm excitation. Ultraviolet (¹I₆ →³F₄/³H₆ and ¹D₂ →³H₆), blue (¹D₂ →³F₄ and ¹G₄ →³H₆), red (¹D₂ →³H₄, ¹G₄ →³F₄, and ³F₃ →³H₆), and near infrared (³H₄ →³H₆) emissions were observed. The results indicated that the relative intensity of the ultraviolet to the blue as well as the blue to the near infrared increased with decreasing the size of nanobundles. Especially, the position of the dominant red emission peak varied with the size of nanobundles. As the length of nanobundles increased to 500 nm, unusual ³F₃ →³H₆ transition was observed, which was theoretically explained considering the decrease of the nonradiative transition rate of ³F₃ →³H₄.
