摘要：
The large-scale novel YPO4:Eu3+ octahedron microcrystals have been synthesized successfully under a facile hydrothermal condition. Field emission scanning electron microscopy and transmission electron microscopy observations indicate that the obtained YPO4:Eu3+ octahedron microcrystals have a diameter of about 1-2 mu m with smooth surface. The luminescent properties with three main emission bands centered at 582, 587 and 610 nm indicate that the YPO4:Eu3+ octahedron microcrystals possess the D-5(0)-F-7(0), D-5(0)-F-7(1) and D-5(0)-F-7(2) transitions from Eu3+. The magnetism property of the synthetic YPO4:Eu3+ octahedron microcrystals is also investigated, and the room temperature ferromagnetism is observed. (C) 2012 Elsevier B.V. All rights reserved.
