CURRICULUM VITAE = 111MasterField emission displays (FEDs) and plasma display panels (PDPs) are of the most promising flat-panel displays. Most available phosphors for FEDs do not have high enough luminescence efficiency at low voltages. Wide band gap semiconductive SrTiO₃host lattice with perovskite structure has been investigated for FEDs. The red luminescence intensity of SrTiO₃was enhanced remarkably by the incorporation of Li^(+) ion as [xSrTiO₃+ (1-x)Li₂TiO₃]:Pr^(3+). The enhanced luminescence is thought to result mostly from the oxygen vacancy generated by Li^(+) ion incorporation in the lattices. BaTi₄O_(9) has a pentagonal-prism tunnel structure. In BaTi₄O_(9):Pr^(3+), two emission peaks are observed at 606 nm and 630 nm which correspond to transition of ¹D₂→ ³H₄. The PL spectrum of Sr_(1-x)Ba_(x)Nb₂O_(6):Pr^(3+) shows the red emission at 608 nm.
For PDPs, (Y,Gd)BO₃:Eu^(3+) is usually used as a red phosphor, which yields an orange color due to the presence of the rather intense ^(5)D_(0) → ^(7)F₁emission line at 591 nm. In order to improve the color purity, the borates which have noncentrosymmetry structure are sought in this work. Vacuum ultraviolet (VUV) excitation and photoluminescence (PL) characteristics of the Eu^(3+) ion activated borate phosphors; BaZr(BO₃)₂:Eu^(3+) and SrAl₂B₂O_(7):Eu^(3+) are studied. The excitation spectra show strong absorption in the VUV region with the absorption band edge at ca. ₂00 nm for BaZr(BO₃)₂:Eu^(3+) and 183 nm for SrAl₂B₂O_(7):Eu^(3+), respectively, which ensures the efficient absorption of the Xe plasma emission lines. In BaZr(BO₃)₂:Eu^(3+), the charge transfer band of Eu^(3+) does not appear strongly in the excitation spectrum, which can be enhanced by co-doping the Al^(3+) ion into the BaZr(BO₃)₂ lattices. The luminescence intensity of BaZr(BO₃)₂:Eu^(3+) is also increased by Al^(3+) incorporation into the lattices. The PL spectra show the strongest emission at 615 nm corresponding to the electric dipole ^(5)D_(0) → ^(7)F₂transition of Eu^(3+) in both BaZr(BO₃)₂ and SrAl₂B₂O_(7), similar to that in YAl₃(BO₃)₄, which results in a good color purity for display applications. The PL intensity has also increased by incorporating La^(3+), however the red color purity has deteriorated because of the increased centrosymmetric nature of the site with the smaller size of La^(3+) than Ba^(2+). With the incorporation of Y^(3+) into the BaZr(BO₃)₂lattice, the PL characteristics of the Eu^(3+) activator resembles that in the YBO₃lattices. The luminescence intensity is the highest with good color purity for BaZr(BO₃)₂:Eu^(3+) incorporated with both Al^(3+) (10 mol%) and La^(3+) (0.5 mol%).
For lighting applications Ca₄YO(BO₃)₃:Eu^(3+) and Ca₄YO(BO₃)₃:Tb^(3+) are excellent red and green phosphors, respectively. In Ca₄YO(BO₃)₃:Eu^(3+), the excitation band appears strongly at ₂50 nm with ca. 100 nm bandwidth, and the resultant emission at ca. 611 nm. The Tb^(3+) ion in Ca₄YO(BO₃)₃also emits efficiently green at 547 nm similar to that in oxides with UV the excitation of the allowed 4f → 5d transition

Effect of electrolytes on electrochemical properties of MmNi(5)-based hydrogen storage alloy
No full textThis Project is financially supported by the National Natural Foundations of China (51261003), the Natural Foundations of Guangxi Province (2012GXNSFGA060002; 2011GXNSFD018004; 201201ZD009) Guangxi Experiment center of information science (20130113) and National students’ Innovative Project (101059530) and National students’ Innovative Project (101059530).The effect of electrolytes on the electrochemical properties of MmNi(3.68)Co(0.72)Mn(0.43)Al(0.17) hydrogen storage alloy electrodes has been investigated at 303 K and 273 K. Three electrolytes (EL1, EL2, EL3) were obtained by adding 2 wt%, 4 wt% and 6 wt% LiOH into the original electrolyte EO (6 M/ L KOH), respectively. The results indicate that the addition of LiOH improves the discharge capacity and cycle life at 303 K and 273 K. The highest maximum capacity and capacity retention (after 50th cycles) have been observed in electrolyte EL2. However, the high-rate dischargeability (HRD) decreases gradually from EO to EL3 at the two temperatures because of the addition of LiOH. The corrosion current I-corr from Tafel Polarization curves (TP) and the resistance of the oxide layer R-ol from electrochemical impedance spectroscopy (EIS) indicates that the alloy electrode worked in EL1 has a better anti-corrosion ability. The real surface area of the electrodes estimated with EIS analysis, decrease from 51.95 cm(2) in EO to 15.6 cm(2) in EL2, but increase to 31.59 cm(2) in EL3 after being fully activated. The additional LiOH improves the anti-pulverization ability of alloy powders, delay the loss of active elements within the alloy electrode, resulting in an inproved capacity retention of alloy electrode. Meanwhile, the electrochemical kinetics analysis suggests that the charge-transfer reaction at the interface of electrode surface and electrolyte is the rate-determining step when tested at 303 K and 273 K.Peer reviewe
