  The phase diagram Ca3−xZnx(PO4)2 has been investigated by31P magic angle spinning NMR (MASNMR). The study demonstrates how MASNMR can be used to make clear distinction between regions of solid solution, line phases, and biphasic mixtures. The31P MASNMR spectrum of the complex phosphate, β-Ca3(PO4)2, has been rationalized in terms of the known structure, and the broadness of the observed resonances

  In order to explore a new family of phosphate phosphors, the synthesis and crystal structure of a novel phosphate family, Ca19M2(PO4)14 (M = Mg, Zn, Mn), were investigated. Eu3+ doped Ca19Mg2(PO4)14 red phosphor was also successfully synthesized with the objective of application in ultraviolet-based light-emitting diodes (LEDs) and field emission displays (FEDs). The characteristic photoluminescence properties were studied in detail by photoluminescence excitation (PLE), emission (PL) spectra and decay times. The Ca19Mg2(PO4)14:0.06Eu3+ phosphor offers higher brightness and thermal stability than the commercial Y2O3:Eu3+. The unexpected temperature-dependent luminescence from higher 5D1 states was observed and was explained via the configuration coordinate diagram. The cathodoluminescence (CL) spectra as a function of accelerating voltage and probe current were also measured. Excellent degradation properties with good color stability were obtained by continuous low-voltage electron-beam excitation of the phosphor. The results indicate that the phosphor Ca19Mg2(PO4)14:0.06Eu3+ can be a suitable red-emitting phosphor candidate for LEDs and FEDs.

  为了探索新的磷酸盐荧光粉家族，我们研究了新型磷酸盐家族 Ca19M2(PO4)14（M = Mg、Zn、Mn）的合成和晶体结构。此外，还成功合成了掺杂 Eu3+ 的 Ca19Mg2(PO4)14 红色荧光粉，并将其应用于紫外发光二极管（LED）和场发射显示器（FED）。通过光致发光激发（PLE）、发射（PL）光谱和衰减时间详细研究了其光致发光特性。与商用 Y2O3:Eu3+ 相比，Ca19Mg2(PO4)14:0.06Eu3+ 荧光粉具有更高的亮度和热稳定性。从更高的 5D1 状态中观察到了意想不到的随温度变化的发光现象，并通过构型坐标图得到了解释。此外，还测量了阴极发光（CL）光谱与加速电压和探针电流的函数关系。通过对荧光粉进行持续的低压电子束激发，获得了具有良好颜色稳定性的优异降解特性。结果表明，Ca19Mg2(PO4)14:0.06Eu3+ 荧光粉可作为 LED 和 FED 的合适红色发光荧光粉。
• Degradation Resistance of Cordierite Diesel Particulate Filters to Diesel Fuel Ash Deposits

  The thermochemical degradation resistance of a typical cordierite diesel particulate filter (DPF) material by synthetic ashes typical of those arising in practice has been investigated over the temperature range 950°C–1250°C. Differential thermal analyses and heat treatment of pressed pellets were used to characterize the melting/transformation behavior of ashes representative of typical diesel fuel (ash A) and those typical of when the catalysts ferrocene (ash FeA) and cerium carboxylate (ash CeA) were present in the fuel and to study the interaction chemistry between powdered cordierite and the ash compositions. Additional experiments involved the application of surface coverings of ash to DPF specimens. The results obtained showed that filter performance would not be compromised by ash liquefaction/sintering as long as temperatures did not exceed 900°C for ash A, 970°C for ash FeA and 1100°C for ash CeA. For long time periods, compared to the expected application durations, liquid phosphates dissolve cordierite leading to the formation of Zn and Fe aluminate spinels. Overall, the results clearly indicate that thermochemical degradation of cordierite by ashes under conditions representative of typical diesel engine systems is highly unlikely at temperatures of 1100°C and below.

  日期：2011.2

  Zn-doped beta-tricalcium phosphate (beta-TCP) is synthesized by the solid-state reaction method. The substitution mechanism of Zn ions in beta-TCP synthesized here is investigated by carrying out a combination of near-edge X-ray absorption fine structure (NEXAFS) measurements and first-principles calculations. From the results of the present study, the substitution site for Zn ions in beta-TCP is successfully determined. (C) 2010 Elsevier B.V. All rights reserved.
