摘要

用沉淀法制备Li+、Na+和Eu3+共掺Gd2O3荧光粉,并与微波-固相法制备的样品进行了比较。通过测量该粉体的XRD、激发光谱和发射光谱,比较了样品的微观结构和讨论了不同合成条件对Gd2O3:Eu3+荧光粉发光特性的影响。结果显示在相同的条件下,对于未掺入Li+的Gd2O3:Eu3+样品比较,沉淀法制备样品的发光强度是微波-固相法制备样品的1.68倍;掺入Li+的Gd2O3:Eu3+样品比较,沉淀法制备样品的发光强度是微波—固相法制备样品的1.82倍。当使用草酸作为沉淀剂,掺杂浓度为Li+(4.5 mol%)、Na+(4.5 mol%)、Eu3+(4.5 mol%),在800 ℃ 煅烧2 h后获得样品的发光强度,是Gd2O3:Eu3+荧光粉的5.91倍。

Abstract

The Gd2O3:Eu3+phosphor co-doped with Li+ and Na+ were prepared by precipitation method and compared with the samples prepared by microwave solid state phase method.The X ray diffraction,the excitation spectra and the emission spectra of the samples were measured.The microstructure of the samples was analyzed,and the effect of different synthesis conditions on the photoluminescence properties of Gd2O3:Eu3+phosphor was discussed.The results showed that without adding Li+ ions,the luminous intensity of the sample obtained by precipition increased about 1.68 times compared with the sample prepared by the microwave solid phase method.Adding Li+ions,the luminous intensity of the sample obtained by precipition increased 1.82 times compared with it obtained by the microwave solid phase method.The emission of the sample with 4.5 mol% Li+,4.5 mol% Na+ and 4.5 mol% Eu3+ co-doped Gd2O3 increased 5.91 times than that of the sample without adding Li+ and Na+ ions by C2H2O4 precipitation.
