Traversing the Periodic Table through Phase‐Separating Nanoreactors

open access: yesAdvanced Materials, EarlyView.
Centimeter‐scale arrays of single nanoparticles, generated through either Dip Pen Nanolithography or Polymer Pen Lithography, allow for the discovery of novel nanomaterials at an unprecedented scale. The development of phase‐separating hydrophobic nanoreactors bypasses element‐specific chemistry limitations, enabling the synthesis of polyelemental ...

3D Hollow MoS2 Architecture Enabled Highly Sensitive SERS Detection

open access: yesAdvanced Materials Interfaces, EarlyView.
A single‐layer MoS2 self‐assembled 3D nanostructure as a novel metal‐free SERS substrate enables effectively improved SERS performance both experimentally and theoretically. The EF and LOD of the substrate reaches 1.68 × 106 and 10−8 M, respectively. The distinct SERS properties are attributed to the enhanced charge transfer between the substrate and ...

Enhancement and suppression of surface plasmon resonance in Ag aggregate by optical gain and absorption in surrounding dielectric medium [PDF]

open access: yesarXiv, 2005
We have observed the compensation of loss in metal by gain in interfacing dielectric in the mixture of aggregated silver nanoparticles and rhodamine 6G dye. The demonstrated six-fold enhancement of the Rayleigh scattering is the evidence of the increase of the quality factor of the surface plasmon (SP) resonance.
