Demand for the transfer of chirality from a pre-engineered nanoparticle to any other metal is fundamental importance developing wide range chirality-related applications. Herein, we show that binary alloy chiral nanoparticles (CNPs) with an engineerable composition can be formed metallic CNPs intrinsic structural serving as sacrificial templates (STs), via galvanic replacement reaction (GRR). This GRR-mediated general phenomenon and results in formation Cu-Ag solid morphology mesoporous made...
Metal chiral nanoparticles (CNPs), composed of atomically lattices, are an emerging nanomaterial showing unique asymmetric properties. Chirality transmission from the host CNPs mediated with galvanic replacement reactions (GRRs) has been carried out to extend their compositional space unary binary. Further extension to, e.g., ternary is fundamental interest and in practical demand. Here, layer-by-layer glancing angle deposition used dope galvanically "inert" dopant Au Cu generate binary...
Circularly polarized light emission (CPLE) can be potentially applied to three-dimensional displays, information storage, and biometry. However, these applications are practically limited by a low purity of circular polarization, i.e., the small optical dissymmetry factor gCPLE. Herein, glancing angle deposition (GLAD) is performed produce inorganic nanohelices (NHs) generate CPLE with large gCPLE values. CdSe NHs emit red = 0.15 at helical pitch (P) ≈ 570 nm, having 40-fold amplification...
In article number 2001473, Zhifeng Huang and co-workers introduce an emerging concept of metal chiral nanoparticles (CNPs), composed lattices at the atomic scale without containing ligands. Metal CNPs are mainly generated by macroscopic shear forces applied with glancing angle deposition, have unique asymmetric properties promisingly leading to prominent applications in fields enantiodifferentiation, catalysis, enantioseperation, bio-imaging bio-sensing.
Second-harmonic generation (SHG) integrated with diverse nonlinear optical activity characterization has high sensitivity to detect the symmetry of materials at an interface, but study is in its infancy. Here, we employ SHG linear dichroism (or SHG-LD) chiroptical origin silver (Ag) chiral nanoparticles (CNPs) deposited by glancing angle deposition (GLAD). It found that Ag CNPs show ascribed not only structural chirality (i.e., atomically lattices) also one-fold anisotropy interface due...
