Effect of local environment in resonant domains of polydisperse plasmonic nanoparticle aggregates on optodynamic processes in pulsed laser fields |
Kinetic parameters of a monodisperse dimer (a) and trimer (b). In the trimer, the interparticle gap of the nearest particles is hij = h 12 = h 23, due to the symmetry of the trimer, and E el denotes the elasticity modulus of the adlayer of the central particle. The laser pulse wavelength is (a) λ = 460 nm, (b) λ = 500 nm. Curve 1 for the initial stage, curve 2 at the pulse end ( t = 20 ps), curve 3 for t = 20 ns. The parameters T e = 103 K, T i = 103 K, E el = 108 N/m2, hij in unit nm. |
