摘要

Y2O3:Eu3+荧光粉是最有前途的氧化基红色荧光粉之一。由于其在紫外线和阴极射线激发下的高效发光，长期以来一直受到人们的研究。Y2O3: Eu3+具有发光特性，可发出611nm波长的红光，适用于许多显示器件。本文主要研究了用共沉淀法获得的Eu+3掺杂Y2O3纳米颗粒的制备、表征和结构性能。通过x射线衍射(XRD)、紫外可见光谱(UV)、透射电子显微镜(TEM)和光致发光等手段对合成的颗粒进行了表征。所有粉末均为结晶良好的球形颗粒，平均晶粒尺寸为85nm。当Eu3+掺杂浓度为5 mol%时，光学性能最佳。

Luminescent properties of nano-sized Y2O3:Eu synthesized by co-precipitation method

Y2O3:Eu3+ phosphor is one of the most promising oxide-based red phosphors. It is being studied since long time because of its efficient luminescence under ultraviolet (UV) and cathode-ray excitation. Y2O3: Eu3+ show luminescent properties and emits red light at a wavelength of 611 nm and was found to be suitable for many display devices. The present study focuses on the preparation, characterization and structural properties of Eu+3 doped Y2O3 nanoparticles obtained by co-precipitation method. The synthesized particles were characterized by X-ray diffraction (XRD), UV visible spectroscopy, Transmission electron microscopy (TEM) and Photoluminescence. All the powders were well crystallized spherical particles with average crystallite size of 85nm. An optimum concentration of 5 mol% Eu3+ doping exhibited maximum optical properties.
