One-step growth of triangular silver nanoplates with predictable sizes on a large scale

Abstract

A one-step growth of triangular silver nanoplates on a large scale is developed by a coordination-based kinetically controlled seeded growth method, with their edge length precisely tuned from 150 nm to 1.5 μm, and surface plasmon resonance extends to full near-infrared.

Design, Fabrication and Characterization of Pressure-Responsive Films Based on The Orientation Dependence of Plasmonic Properties of Ag@Au Nanoplates

“…AgNPLs with tunable size and uniform shape can be synthesized via seeded growth method 26–29 , however, the stability of AgNPLs in the polymer matrix is a challenging due to oxidation by surfactant-assisted etching. Ag@Au NPLs obtained by epitaxial growth of a layer of gold on silver can enhance their stability.…”

Large scale synthesis and formation mechanism of silver nanoparticles in solid-state reactions at ambient temperature

“…Also, various shape-controlled Ag nanostructures including quasispheres [43], decahedrons [44], cubes [45], prisms [46], rods [47], wires [48], tubes [49], branches [50], sheets [51], plates [52] and belts [53] have been reported. However, to the best of our knowledge, there is no report concerned with AgNPs synthesis based on solid state reactions at ambient temperature so far.…”

Localized Surface Plasmon Resonance of Silver Nanotriangles Synthesized by a Versatile Solution Reaction

“…Under the same amount of ingredient for crystals to grow, the more seeds concentration indicates the more nucleation sites and the shorter size of the nanocrystals [31]. A relationship between the edge length (L) and the volume of the seeds solution (V), L 2.437 = kV −1 (k is a constant), was summarized in Liu's work [24]. The shape evolution probably derived from the fact that the vertex atoms of the nanotriangles are more labile than other surface atoms, and they will migrate to the sides of the triangle to lower the surface energy [32].…”

“…For the past decade, many authors reported the solution-phase methods for preparing the silver nanotriangles [18][19][20][21][22][23][24][25][26]. One of the most often used methods is the production of silver nanotriangles from Ag + salts solution by exposure to UV-vis radiation or via chemical reduction.…”
