Hydrothermal Synthesis of 3-Dimensional Flower-Like Y2O3:Eu3+ Microstructures and the Luminescence Properties
In this work, 3-dimensional flower-like Y2O3:Eu3+ microstructures were synthesized through a facile route using simple hydrothermal reaction and sequentially calcinations without templates or matrix. The flower-like micro-architectures are self-assembled by nanosheets with thickness of about 50 nm and diameter about 3-5 μm, which were verified by the field-emission electron microscopy (FESEM) and transmission electron microscope (TEM). The as-synthesized Y2O3:Eu3+ samples show a strong red emission due to 5D0-7F2 transition (612nm), suggesting potential applications in red phosphors.
