- 摘要：
- The luminescent properties of phosphors are sensitive to the size of phosphor particles. The commercial Y2SiO5:Tb3+ phosphors usually show relatively larger particle size (5-10 mu m) due to the irregular morphology of rare earth oxide precursor and thus degrade the luminescent properties. In this paper, we report the Y2SiO5:Tb3+ phosphors synthesized from the uniform Tb-doped Y2O3 precursor by a homogeneous precipitation method. Compared with the commercial phosphors, the obtained Y2SiO5:Tb3+ phosphors manifest the uniform morphology with much smaller particles distributing from 0.8 mu m to 1.9 mu m. Consequently, the cathodoluminescent intensity under low excitation voltage (1-5 kV) was increased, demonstrating a strong green emission with a dominant wavelength of 545 nm. Our results indicate an effective way to develop the high-quality phosphors for field emission display.
