Controllable Synthesis of Monodisperse CaF2 microsphere and the investigation on luminous performance of CaF2:Ce3+/Tb3+

Sun Q., Sun X., Hu X.Y., Fan J., Zhan S.C., Wang Y., Wang Z.Z., Wang Y., Wang Z.Z., Sun Q., Sun X., Hao Y.Y., Northwest University, CN

Highly uniform and well-dispersed CaF2 microsphere and hollow spheres with tunable particles size (100nm-900nm) have been successfully synthesized by a facile hydrothermal process using ethylenediaminetetraacetic acid disodium as a complexing reagent. The XRD results indicated [...]

Green, Cubic Y2O3: Tb3+ Nanospheres: Synthesis and Photoluminescence Property

Miao H., Hu X.Y., Sun Q., Sun X., Wang Z.Z., Sun Q., Sun X., Zhang D.K., Bai J.T., Hou X., Northwest University, CN

Tb3+-doped Y2O3 green nanospheres were prepared via the simple, cost-effective urea homogeneous precipitation method without additives. Nanospheres were characterized by X-ray diffraction, Scanning electron microscope, Photoluminescence spectroscopy. The specimens annealed above 800oC are well matched [...]

Polymer-based gene delivery system fabricated with the participation of a polyanion

Sun Q., Stolnik S., University of Nottingham, UK

A DNA/polycation/polyanion system is being designed, which is supposed to be a potentially improved system in comparison to the traditional gene delivery system (DNA/polycation system). The production of such a DNA/polycation/polyanion system is based on [...]
