“We report the optical and magnetic properties of ZnO, Zn(0.97)In(0.03)O, and Zn(0.94)In(0.06)O nanowires (NWs). All samples have similar wirelike shape with an average diameter of about 70 nm and a length of about 10 mu m. The comparison of photoluminescence (PL) spectra at 10 K indicated that a new broad emission band appeared after indium doping, which is associated with donor-acceptor-pair recombination. Additionally, the intensity of oxygen-vacancies-induced visible emission increased with increasing In content, indicating that In doping

can induce many oxygen vacancies. Furthermore, magnetic measurements PCI-32765 mouse revealed that pure ZnO NWs are diamagnetic, while indium-doped ZnO NWs exhibit intrinsic ferromagnetism at room temperature. With the increase in In content, the coercive field and the magnetic moment for indium-doped ZnO NWs increase largely. Ferromagnetic ordering can be interpreted as being due to O vacancies induced by In doping, which is in good agreement with PL results. (C) 2010 American Institute of Physics.

“Relationship

between adhesion properties and phase structures of styrene triblock and diblock copolymer blends was investigated in detail. For this purpose, polystyrene-block-polyisoprene-block-polystyrene triblock and polystyrene-block-polyisoprene diblock copolymers were used and the diblock content was varied from 0 to 100 wt All blends formed the sea-island structure in which S63845 spherical polystyrene domains were dispersed in polyisoprene matrix and mean domain size was 20 nm. The domain size was slightly affected by the diblock content. The fracture stress and strain measured by a tensile test decreased and the molecular mobility measured by a (1)H pulse nuclear magnetic resonance analysis increased with an increase of diblock content. The tack as adhesion property increased Cyclopamine order with an increase of diblock content below 70 wt %), then decreased over 70 wt To. The cohesive strength decreased and the interfacial adhesion increased with an increase of diblock content. The tack increases by the development of cohesive

strength and interfacial adhesion. Therefore, the tack showed the maximum at the optimum contribution balance between cohesive strength and interfacial adhesion. (C) 2010 Wiley Periodicals, Inc. J Appl Polym Sci 118: 1766-1773, 2010″
“The afterglow of Eu(2+) activated SrMg(2)(PO(4))(2) can be greatly enhanced by the codoping of Gd(3+), as well as an interesting phenomenon of the improvement of the efficiency of the excitation light. However, Eu(2+) activated BaMg(2)(PO(4))(2) does not show the phosphorescence until the codoping of Gd(3+). It is suggested that the codoping of Gd(3+) improve the electron storage ability of material by acting as electron-trapping centers resulted from the nonequal-valence substitution of Gd(3+) replacing Sr(2+) and Ba(3+).
