Abstract

We have developed a method for obtaining a direct pattern of silver nanoparticles NPs on porous silicon p-Si by means of inkjet printing IjP of a silver salt. Silver NPs were obtained by p-Si mediated in-situ reduction of Ag cations using solutions based on AgNO3 which were directly printed on p-Si according to specific geometries and process parameters. The main difference with respect to existing literature is that normally, inkjet printing is applied to silver metal NP suspensions, while in our experiment the NPs are formed after jetting the solution on the reactive substrate. We performed both optical and scanning electron microscopes on the NPs traces, correlating the morphology features with the IjP parameters, giving an insight on the synthesis kinetics. The patterned NPs show good performances as SERS substrates.
