Title: Energy transfer and heat-treatment effect of photoluminescence in Eu{sup 3+}-doped TbPO{sub 4} nanowires

Abstract

We have successfully synthesized Eu{sup 3+}-doped TbPO{sub 4} nanowires, which are orderly organized to form bundle-like structure. A thermal treatment up to 600 deg. C does not modify the size, shape and structure of as-synthesized sample. Due to the energy overlap between Tb{sup 3+} and Eu{sup 3+}, an efficient energy transfer occurs from Tb{sup 3+} to Eu{sup 3+}. The effects of Eu{sup 3+} concentration and thermal treatment on the luminescent properties of Eu{sup 3+} are investigated. The increase of Eu{sup 3+} concentration leads to the increase of the energy transfer efficiency from Tb{sup 3+} to Eu{sup 3+}, but also enhances the probability of the interaction between neighboring Eu{sup 3+}, which results in the concentration quenching. With the heat-treatment, the luminescence of Eu{sup 3+} presents an obvious increase, but almost no change for the luminescence of Tb{sup 3+}. This difference is explained based on the TGA, DTA, and fluorescent decay dynamics analyses. - Graphical abstract: The energy transfer from Tb{sup 3+} to Eu{sup 3+} occurs in the Eu-doped TbPO{sub 4} nanowires synthesized by the hydrothermal route.
