Optical Limitation induced by Gold Clusters. 1. Size Effect

Abstract: The nonlinear optical response of gold particles (with 2.5, 9, or 15 nm radius) prepared by γ-radiolysis in water solution and stabilized by poly(vinyl alcohol) is size-dependent. The 2.5 nm clusters do not limit light transmission even at very high fluence of nanosecond laser pulses, while the larger clusters strongly limit the laser beam transmission at 530 nm. The threshold of limitation and the amplitude depend on the size of the particles. The rise of the optical limiting effect is measured by picosecond … Show more

“…7 Because of this, there are many interesting nonlinear optical properties of metal nanoparticles or nanorods that give immense enthusiasm for their use in applications such as optical limiting device, plasmon waveguide, sensor protection, medicine, and nanoprobes. [8][9][10][11] However, the saturable and reverse saturable absorption at longitudinal SPR in metal nanorods have not been explored and reported yet. In this letter, we report our investigations of resonant, saturable and reverse saturable absorption of longitudinal surface plasmons in gold nanorods (Au NRs).…”

“…The data for the SWNTs suspension recall the behavior of non-linear scattering systems, such as carbon black or gold clusters. 52 The hypothesis that the dominant mechanism of limitation is different for the suspension and for the solubilized NTs and that, particularly for the latter, there is a dominant excited state absorption, was already suggested by Sun and coworkers. 22 Further investigations are however needed to confirm the above hypothesis.…”
