Facile and Low-Cost Fabrication of SiO<sub>2</sub>-Covered Au Nanoislands for Combined Plasmonic Enhanced Fluorescence Microscopy and SERS

Facile and Low-Cost Fabrication of SiO<sub>2</sub>-Covered Au Nanoislands for Combined Plasmonic Enhanced Fluorescence Microscopy and SERS

An easy and low-cost way to fabricate monometallic Au nanoislands for plasmonic enhanced spectroscopy is presented. The method is based on direct thermal evaporation of Au on glass substrates to form nanoislands, with thicknesses between 2 and 15 nm, which are subsequently covered by a thin layer of...
