Direct Laser Annealing of Surface‐Enhanced Raman Scattering Substrates

Abstract: A laser‐annealing technique for the fabrication of surface‐enhanced Raman scattering (SERS) substrates consisting of closely packed gold nanoparticles (AuNPs) with high densities and small separation distances is reported. Laser annealing enables strongly localized interaction between the laser spot and the colloidal AuNPs within the irradiation area. Multiple stages of the alternative spin‐coating of colloidal AuNPs and laser‐annealing processes enable filling of the gaps between the AuNPs by newly produced o… Show more

“…Additionally, laser annealing is a type of localized annealing that has been widely studied in device preparation because of its advantages, such as fast annealing speed, low heat accumulation, selectable annealing region, localized thermal effect, and good spatial resolution [ 28 , 29 ]. However, this treatment is almost exclusively used in inorganic materials, and laser annealing treatment is hardly used in devices prepared based on organic materials due to their low heat resistance and poor stability [ 30 , 31 , 32 , 33 ].…”
