Synthesis of Poly(ST-co-COPSI)particles by soap-free emulsion copolymerization and its optical properties as photonic crystals

, , , ,
Highly charged, submicron-sized polymeric colloidal particles can self assemble into 3-dimentional(3D) opal structure which is useful template for photonic crystal. In this report, optical properties of poly[Styrene(ST)-co-Allyloxy-2-hydroxypropane sulfonic acid sodium salt(COPSI)] polymeric microspheres with number [...]

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

, , , , , , , , , , ,
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 [...]

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

, , , , , , , , , , , , ,
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 [...]

Round Monodisperse Nanodiamonds: Towards Highly Bright, Biologically Inert Probes for Fluorescence Imaging

, , , , , , , , , , , ,
Fluorescent nanodiamonds (FNDs) are extremely promising luminescent probes and sensors in biomedical research, possessing unique properties such as absolute photostability and high biocompatibility. Here we present a complex route towards bioapplicable FNDs. First we developed [...]

Monodisperse Thermo-responsive Composite Microgels with Core-shell Structure based on Au@Ag Bimetallic Nanorod as Core: Fabrication and Application in SERS Substrate

, , ,
In summary, monodisperse Au@Ag bimetallic nanorod is encapsulated by crosslinked poly(N-isopropylacrylamide) (PNIPAM) to produce thermo-responsive composite microgel with well-defined core-shell structure (Au@AgNR@PNIPAM microgel) by seed-precipitation polymerization method using butenoic acid modified Au@AgNRs as seeds. Their [...]
