Y203:Yb3+/Er3+ hollow spheres with controlled inner structures and enhanced upconverted photoluminescence

Zong, Lingbo and Xu, Pengfei and Ding, Yunji and Zhao, Kun and Wang, Zumin and Yan, Xuecheng and Yu, Ranbo and Chen, Jun and Xing, Xianran (2015) Y203:Yb3+/Er3+ hollow spheres with controlled inner structures and enhanced upconverted photoluminescence. Small, 11 (23). pp. 2768-2773. ISSN 1613-6810


Multishell Y2O3:Yb3+/Er3+ hollow spheres with uniform morphologies and controllable inner structures are prepared successfully by using a glucose-template hydrothermal process followed by temperature-programmed calcination. Much enhanced upconverted photoluminescence of these Y2O3:Yb3+/Er3+ are observed, which are due to the multiple reflections and the enhanced light-harvesting efficiency of the NIR light resulting from the special features of the multishell structures.
