摘要：

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. © 2015 WILEY-VCH Verlag GmbH & Co.
