| Description |
Temperature (T)-dependent optical response of gold nanoparticle (NP) dimer of radii, 5-60 nm surrounded by air Medium is simulated and studied using finite element method (FEM). Temperature-dependent damping parameter from Drude-Lorentz dielectric model having contribution from different scattering, mechanisms and volume expansion is taken into,consicleration for studying surface plasmon resonance (SPR) behavior. A red shift and band broadening of SPR. is observed with increase in temperature for all sizes with significant shift for dimes of radii 40-60 nm. A size-independent parameter is extracted from the study, showing similar temperature-dependence, irrespective of dimer size, and can be used as an important parameter in temperature sensing.
