| 2 | Effect of La_2O_3 on electrical friction and wear properties of Cu-graphite composites显示文摘Sliding friction and wear experiments using Cu-La2O3-graphite composites against Cu-5 wt.%Ag alloy ring were conducted at a constant sliding speed of 10 m/s, a current density of 10 A/cm2 and a load of 2.5 N/cm2. These composites with different La2O3 and graphite contents were fabricated by hot-pressing. Physical and mechanical properties of the composites were examined. Morphologies of the worn surface of composites were observed using optical microscopy. X-ray photoelectron spectroscopy spectra were used to study compositions of the lubricating film. The results showed that with the increasing addition of La2O3, hardness, flexural strength and electrical resistivity increased, but the relative density dropped. The friction coefficient increased with the increasing addition of La2O3. Composite containing 3 vol.% of La2O3 and 37 vol.% of graphite showed the best wear resistance. The main wear mechanisms of composites were abrasive wear, oxidative wear and adhesive wear. | 莫飞 凤仪 陈阳明 王雨晴 钱刚 豆亚坤 张学斌 | 2015 | Journal of Rare Earths2015，33，3： | 5 |
| 3 | Effect of starting composition and post-anneal on the structure and luminescence properties of Eu-doped Ca-α-SiAlON phosphors prepared by combustion synthesis显示文摘Eu-doped Ca-α-SiAlON yellow phosphors, with the compositions Ca0.72Eu0.08Si9.56Al2.44O0.84N15.16, were prepared by a highly efficient combustion synthesis method. By optimizing the starting compositions of reactants and choosing appropriate post-annealing conditions, phase-pure, uniform and fine Ca-α-sialon:Eu2+ phosphors possessing the particle size ranging ~3–5 μm, and good luminescence properties with an intense emission band that peaks at 592 nm under n-UV or blue light excitation were obtained. The results indicated that combustion synthesis method was an energy efficient, time saving and low cost way to prepare Ca-α-SiAlON phosphors by controlling the mass ratio of comburents. A combination with post-annealing treatment was desired for further increase of the properties of Ca-α-SiAlON phosphors. | 陈莹 袁轩一 陈克新 崔巍 葛一瑶 | 2014 | Journal of Rare Earths2014，32，6： | 5 |

| 5 | Li3PO4:M(M=Tb,Cu)phosphors for radiation dosimetry显示文摘The dosimetric phosphors Li_3PO_4:M(M=Tb, Cu) were produced by modified solid-state method.The structural and morphological characterization was carried out through X-ray diffraction(XRD) and scanning electron microscope(SEM). Additionally, the photoluminescence(PL), thermoluminescence(TL) and optically stimulated luminescence(OSL) properties of powder Li_3PO_4 doped with Tb and Cu were studied. It is advocated that Li_3PO_4: Cu phosphor not only shows higher OSL sensitivity(25 times or more) but also gives faster decay in OSL signals than that of Li_3PO_4: Tb^(3+) phosphor. The minimum detectable dose(MDD) of Li_3PO_4:M(M=Tb,Cu) phosphors is found to be 21.69 × 10^(-3) and 3.33 ×10^(-6) J·kg^(-1),respectively. In OSL mode, phosphor shows linear dose response in the range of 0.02-20.00 J·kg^(-1).In TL mode, sensitivity of Li_3PO_4: Cu phosphor is more than that of Li_3PO_4: Tb phosphor. The kinetics parameters such as activation energy and frequency factors were determined by peak shape method, and photoionization cross sections of prepared phosphor were calculated. | Chetan B.Palan Nikhilesh Bajaj Anuj Soni Mukund Kulkarni Shreeniwas Omanwar | 2017 | Rare Metals2017，36，9： | 0 |
