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 · 7,741 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlepH Mediated Control Synthesis of Lanthanide-Doped YPO4 Upconversion Nano/MicrocrystalsMeiling Tan, Shuwei Hao, Xiangbin Meng et al.A pH-mediated rational control over the phase transformation, morphology and size of lanthanide doped YPO4 nano/microcrystals has been accomplished using a hydrothermal route. The morphology of the resulting particles evolves from the spheres, to the nanoflakes and finally to the nanorods when increasing the pH value of the reaction solution from 1 to 9, while the induction of crystal phase … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 3 · 1 Jun 2015 · 7,936 accessesView PDFCite
