“…Rare-earth penetration [16,18] is a new material modification method to make rare-earth cations penetrate into ceramic material driven by the concentration gradient and thermal motion. Rare-earth penetration technology has been a suitable way to lower the resistivity of BaTiO 3 powders because BaTiO 3 is porous and easy for rare-earth cations to penetrate [19][20][21]. We have conducted plenty of experiments by using different species of rare-earth element to lower the resistivity of BaTiO 3 powders [16,21].…”

The Cu@BaTiO 3 powders were synthesised by a simple low-cost hydrothermal method for the very first time. The effects of copper (Cu) contents on the formation of core(Cu)@shell(BaTiO 3) powders have been investigated by X-ray powder diffraction, scanning electron microscopy and energy dispersive spectrometer. Notably, the existence of Cu@BaTiO 3 powders can only be obtained when Cu content happened to be 20%. A novel modification method, gaseous rare-earth penetration, has been adopted to reduce the resistivity and prepare Cu@BaTiO 3 conductive powders. The results indicated that rare-earth penetration turned out an effective way to lower the resistivity of Cu@BaTiO 3 powders significantly. Surprisingly, the core-shell structure of Cu@BaTiO 3 powders has not perished after rare-earth penetration. Furthermore, the resistivity of Cu@BaTiO 3 conductive powders turned out to be 8.30 × 10 −4 Ω m, which can be a promising candidate for novel and environmental-friendly conductive powders.

Hydroxyl groups in the coordination complex {[Eu(L) 3 (phen)]ÁH 2 O} 2 (L ¼ 6-hydroxy-1-naphthoate and phen ¼ 1,10-phenanthroline) were used to react with ANCO functional groups of isophorone diisocyanate in the presence of dibutyltin dilaurate. A series of new luminescent Eu III -complex-polyurethane acrylate materials, poly(Eu III -complex-polyurethane methacrylate (PUA complex)), were prepared through in situ polymerization of polyurethane acrylate macromonomers and the resulting material was characterized by X-ray diffraction, IR spectra, thermogravimetry analysis, dynamic mechanical analysis, and fluorescence spectroscopy. The result indicates that both Eu III complex and PUA complex can emit characteris-tic fluorescence of Eu III ion. Moreover, the emission intensity was enhanced under the same experiment condition when the content of Eu III complex in the PUA complex was increased. In addition, we have not found the fluorescence quenching in this work even the content of Eu III complex was increased to 5 wt %. Such rare-earth complex-polyurethane acrylate hybrid materials are suitable for the photoluminescent applications. V C 2012 Wiley Periodicals, Inc.
