Thermoresponsive plasmonic core–satellite nanostructures with reversible, temperature sensitive optical properties

Author affiliations

Abstract

Herein is described a facile method for the assembly of plasmonic gold nanoparticles into smart plasmonic core–satellite nanostructures that allow for the dynamic and reversible tuning of the localised surface plasmon resonance using temperature. This smart system takes advantage of the thermoresponsive polymer linker that modulates the gap distance between the core and satellites in response to the temperature, resulting in the tuning of the surface plasmon coupling and resultant optical shift. It permits optical shifts over a wide wavelength range and reversible control of the optical properties by altering the temperature, which may allow these systems to become candidates for temperature sensitive nanosensors.
