Seed‐Mediated Growth of Colloidal Metal Nanocrystals

Abstract

Seed-mediated growth is a powerful and versatile approach for the synthesis of colloidal metal nanocrystals. The vast allure of this approach mainly stems from the staggering degree of control one can achieve over the size, shape, composition, and structure of nanocrystals. These parameters not only control the properties of nanocrystals but also determine their relevance to, and performance in, various applications. The ingenuity and artistry inherent to seed-mediated growth offer extensive promise, enhancing a number of existing applications and opening the door to new developments. This Review demonstrates how the diversity of metal nanocrystals can be expanded with endless opportunities by using seeds with well-defined and controllable internal structures in conjunction with a proper combination of capping agent and reduction kinetics. New capabilities and future directions are also highlighted.

Surfaces enhanced with film-coupled silver nanopolyhedrons for optical transmittance

“…For normal incidence, for which q i ¼ q t ¼ 0, eqn (2) shows that when z 1 ¼ z 2 the reection is eliminated. For normal incidence, any medium whose wave impedance has the vacuum value will be reectionless in the vacuum.…”

“…[1][2][3][4][5][6][7] Controlled synthesis of noble-metal nanoparticles in terms of size and shape has been strongly motivated by the requirements to uncover and map their size-and shapedependent properties and to achieve their practical applications. [8][9][10][11][12] Silver (Ag), in particular, a noble metal historically used in the fabrication of ornaments, electrical conductors, mirrors, antimicrobial coatings, and photographic lms [13][14][15][16][17] has received ever increasing attention when it is in the form of nanocrystals because of their superior performance in a broad range of applications such as catalysis, electronics, optical labeling, and biosensing.…”

Molecular Dynamics Simulations of Silver Nanoparticles of Cubic and Bipyramidal Shape

“…In recent years, particular attention has been paid to synthesis and characterization of sharp-edged AgNPs [4], because their optical, electronic and catalytic properties are strongly dependent on the number of constituent atoms and morphology [1,[5][6][7]. The simple chemistry enables the tuning of these properties by varying the shape, ratio and number of the corners and edges that holds promise for their applications in many industrially and technologically important phenomena, ranging from chemical engineering to nano-science [8][9][10][11].…”

“…The simple chemistry enables the tuning of these properties by varying the shape, ratio and number of the corners and edges that holds promise for their applications in many industrially and technologically important phenomena, ranging from chemical engineering to nano-science [8][9][10][11]. However, the complex interplay among the physico-chemical properties, such as size, morphology, charge, and ligand coating, often makes the interpretation of the experimental results difficult [6,7].…”

Engineering Single Nanopores on Gold Nanoplates by Tuning Crystal Screw Dislocation

“…This is further demonstrated by the selected area electron diffraction (SAED) measurement taken from single Au nanoplate (Figure 1d) where the diffraction pattern can be attributed to single crystalline Au with parallel stacking faults. [41, 42] …”
