摘要：
We observed a simultaneous enhancement of luminescence and magnetization performance in Gd2O3: Yb/Er and Gd2O3: Yb/Ho nanocrystals (NCs) after the Zn2+ ions were doped into them by a simple wet-chemical route. Besides, the enhanced upconversion (UC) emission excited by 1560 nm laser and the paramagnetic properties in Gd2O3: Yb/Er/Zn NCs were reported for the first time. This opens a new window for studying the cooperation of the ion doping effect on improving UC luminescence and magnetic properties of Gd2O3 NCs. (C) 2016 Elsevier B. V. All rights reserved.
