Publikováno v: J. Phys. Chem. C 120 (2016) 27003-27012

Trisoctahedral (TOH) shaped Au nanocrystals (NCs) have emerged as a new class of metal nanoparticles (MNP) due to its superior catalystic and SERS activities caused by the presence of high density atomic steps and dangling bonds on their high index f

Local Electron Beam Excitation and Substrate Effect on the Plasmonic Response of Single Gold Nanostars

Autor: Das, Pabitra, Kedia, Abhitosh, Kumar, Pandian Senthil, Large, Nicolas, Chini, Tapas Kumar

We performed Cathodoluminescence (CL) spectroscopy and imaging in a high resolution scanning electron microscope to locally and selectively excite and investigate the plasmonic property of a multibranched gold nanostar on silicon substrate. This meth
