Research ArticleOpen accessPhrase in the titleA General Strategy to Enhance Upconversion luminescence in Rare-Earth-Ion-Doped Oxide NanocrystalsGuanying Chen, Lei XuWe report a general strategy to enhance upconversion luminescence from rare-earth-doped oxide nanocrystals through tailoring the local crystal filed around rare earth ions. We show that upconversion luminescence from oxide nanocrystals of various host lattice (Y2O3, Gd2O3 and ZnO) and of diverse rare-earth-ions (such as Er3+, Yb3+/Er3+, Yb3+/Ho3+ and Yb3+/Tm3+) was enhanced by orders of magnitude through an introduction of … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 18 Feb 2016 · 7,735 accessesView PDF Cite
