Synthesis and Luminescent Properties of YPO4:Eu3+ Cornflakes Self-Assembled by Nanocrystals

Abstract

A large-scale novel YPO₄:Eu³⁺ cornflakes self-assembled by nanocrystals were synthesized by a facile hydrothermal method. X-Ray diffraction results show that the cornflakes are pure tetragonal structure. Transmission electron microscopy and selected area electron diffraction studies indicate that the YPO₄:Eu³⁺ cornflakes are polycrystalline structure with a narrow size distribution. Photoluminescence spectra results demonstrate that the YPO₄:Eu³⁺ cornflakes have two strong ⁵D₀/⁷F₁ (590 nm) and ⁵D₀/⁷F₂ (616 nm) transition peaks corresponding to orange-red and red colour, respectively.
