| 1 | Size, phase-controlled synthesis,the nucleation and growth mechanisms of NaYF_4:Yb/Er nanocrystals显示文摘Near-monodisperse NaYF_4:Yb/Er nanoparticles(NPs) with controlled size, phases(α,β) and shapes(sphere, and hexagonal plate) were synthesized by adjusting the NaF to RE(RE = Y, Yb, Er) ratios, the reaction temperature and time in the hot surfactant solutions(oleic acid, 1-octadecene) from the improved one-pot thermal decomposition metal trifluoroacetate, and the precursors were prepared via hydrothermal route. The growth kinetics of β-NaYF4 NPs includes several stages: nucleation, growth of aNaYF4, Ostwald ripening, size shrinkage and growth. The results prove that the temperatures are preferred to the phase transformation compared with the NaF content when other experimental conditions are unchanged. Our work will further facilitate the comprehension of the nucleation and growth mechanisms of the NPs, and provide guidance for their controlled synthesis. | Songtao Liu Gejihu De Yueshan Xu Xian Wang Yuanyuan Liu Chunyan Cheng Jianxun Wang | 2018 | Journal of Rare Earths2018，36，10： | 6 |

| 7 | Shape-Controlled Synthesis and Upconversion Luminescence of Y2O3: Yb, Er Microstructures显示文摘The Y2O3: Yb3+ , Er3 + microstructures were fabricated by a hydrothermal method without surfactants.The microstructures structure was characterized by X-ray diffraction (XRD) and scanning electron microscope (SEM,KYKY 1000B).The up-conversion luminescence spectra were studied under 978 nm laser diode excitation.In Yb3 + and Er3 + codoped Y2 O3 microcrystals, the relative intensity of green emission became stronger as the morphology of sample changed from wires to films. | De Gejihu Qin Weiping Zhang Jisen Zhao Dan | 2004 | Journal of Rare Earths2004，22，z1： | 0 |
