中文摘要：
利用Triton X-100／正己醇／环己烷／正己烷／水制成W／O微乳反胶团体系制备Gd2O3：Yb，Er上转换材料。利用扫描电镜观察氧化物粉体的颗粒形貌均为球形；通过改变掺杂元素Yb和Er的比例，在980nm的红外光激发下，观察研究氧化物颗粒的发光性质。该粉体在波长为980nm的半导体激光器激发下发射出绿色和红色的上转换荧光，分别对应于Er^3＋离子的。^S3／2／^2H11／2→^4I15／2跃迁和。^F9／2→^I15／2跃迁。
英文摘要：
Infrared-to-visible upconversion phosphors Gd2O3：Yb,Er with spheral shape were synthesized by using a stable microemulsion system, which included triton X-100, n-hexanol, cyclohexane and water. Red and green upconversion luminescence was obtained under 980 nm infrared excitation. Effect of different proportion in [Yb^3＋] and [Er^3＋] on the intensity of upconversion emission was also investigated.
