Surface plasmons induced at metal surfaces generate remarkable enhancements of localized electric fields as a result of interactions with incident light fields. This is called localized surface plasmon resonance (LSPR). In this study, we report a simple technique for transferring LSPR-active gold and Au\text{core--Ag\text{shell nanoparticles from an aqueous to a toluene phase using octadecylamine molecules for organic-solution processing. The changes in optical properties and size dependence of transfer behavior of the nanoparticles were evaluated by absorption spectroscopy and transmission electron microscopy (TEM). The upper limit of the size of particles that can be transferred into an organic phase is about 25 nm. We also fabricated an LSPR-active colloidal monolayer film on a solid support by solvent evaporation of a colloidal organic solution.
