Assembly of Silver Nanoparticles into Hollow Spheres Using Eu(III) Compound based on Trifluorothenoyl-Acetone

Abstract

The preparation of luminescent silver hollow spheres using Eu(III) compound based on trifluorothenoyl-acetone is described. The structure and size of silver hollow spheres were determined by TEM images. The result shows the formation of hollow structure and average size of the silver hollow spheres (0.9 μm). The silver hollow spheres were further characterized by UV absorption spectrum, SNOM and SEM images, suggesting them to be formed by self-assemble of some isolated silver nanoparticles. The luminescent properties of them were also investigated and they are shown to be high emission strength; moreover, they offer the distinct advantage of a lower packing density compared with other commercial luminescent products.

Template synthesis of hollow silver hexapods using hexapod-shaped silver oxide mesoparticles

“…This galvanic replacement method is appropriate for fabricating hollow Au, Pt, or Pd nanoparticles, but it is difficult to use the same technique to make hollow Ag particles, because Ag particles, themselves are used as the template in this method, and the standard reduction potential of Ag is relatively low. Therefore, only a few papers on the synthesis of hollow Ag particles have been published so far [24][25][26].…”

Effects of Activated Time on Structural Properties of Plated Plant Fiber Nonwoven Sheets

“…The sheets were immersed in an activated solution composed of PdCl 2 (0.15 and 0.015 g/L) and 20 g/L H 3 BO 3 (the pH value was adjusted to 2 by HCl) at 25 C for 1, 2, 4, 8, 16, 32 and 64 min. Then the activated sheets were put into the electroless nickel plating bath containing Na 3…”

“…The metalization of plant¯ber nonwoven sheets has application prospect, such as surface protection, [1][2][3] microelectronics industry, 4 surface decoration 5 and fabrication of biological devices, 6 due to soft, good deformation and excellent electrical conductivity. 1,2 There are several methods to prepare the metalization of nonwoven fabrics such as electroplating, electroless plating, vacuum deposition and magnetron sputtering.…”

Design, synthesis and applications of core–shell, hollow core, and nanorattle multifunctional nanostructures

“…135 Furthermore, 50 nm silver spheres having wall thicknesses of 3-5 nm and 10-15 nm diameter inner cavities were also obtained by implementing a soft templating approach. 138 In addition, further complex hollow cage-like silica spheres loaded with iron oxide nanoparticles in their porous shells have been fabricated using the oil-in-diethylene-glycol microemulsion approach. 139 Zoldesi et al have prepared monodisperse SiO 2 hollow spheres using polydimethylsiloxane (PDMS) silicone O/W emulsion templating.…”
