Journal ArticleDOI
Production of Monodisperse Gold Nanobipyramids with Number Percentages Approaching 100% and Evaluation of Their Plasmonic Properties
TL;DR: In this paper, a method for producing Au NBPs with number percentages approaching 100% and longitudinal plasmon resonance wavelengths synthetically tuned from ≈700 to ≈1200 nm is reported.
Journal ArticleDOI
(Gold core)/(titania shell) nanostructures for plasmon-enhanced photon harvesting and generation of reactive oxygen species
TL;DR: In this article, a facile route to (gold nanocrystal core)/(titania shell) nanostructures with their plasmon band synthetically variable from ∼700 nm to over 1000 nm was reported.
Journal ArticleDOI

Soroosh Daqiqeh Rezaei,Zhaogang Dong,John You En Chan,Jonathan Trisno,Ray J. H. Ng,Qifeng Ruan,Cheng-Wei Qiu,N. Asger Mortensen,Joel K. W. Yang +8 more
TL;DR: Structural colors traditionally refer to colors arising from the interaction of light with structures with periodicities on the order of the wavelength as mentioned in this paper, and have been broadened to include other colors.
Journal ArticleDOI
Growth of Monodisperse Gold Nanospheres with Diameters from 20 nm to 220 nm and Their Core/Satellite Nanostructures
TL;DR: In this article, a simple seed-mediated growth method aided with mild oxidation was used to produce shape-controlled Au nanocrystals with high monodispersity over a large range of sizes.
Journal ArticleDOI
